Ready NodesVMWare Virtual SANVMware's Virtual SAN (vSAN) brings performance, low cost and scalability to virtual cloud deployments running on HPE hardware. An issue the cloud deployment model raises is the problem of adequate storage performance to virtual instances. Spinning disks and limited bandwidth networks lower IO rates over local drives. VMware’s solution to this is vSAN, which adds a temporary local storage “instance” in the form of a solid-state drive to each server. vSAN extends the concept of local instance storage to a shareable storage unit in each HPE server, where additionally, the data can be accessed by other servers over a LAN. The benefits of VSAN include:• Increased performance due to local server access to Flash storage• Lower infrastructure cost by removing the need for networked storage appliances • Highly scalable --simply add more servers to increase storage • Eliminate boot storms since data is stored locally• Unified management --no storage silo versus server silo separation problemsMellanox 10/25G Ethernet interconnect solutions enable unmatched competitive advantages in VMware environments by increase efficiency of overall server utilization and eliminating I/O bottleneck to enable more virtual machines per server, faster migrations and speed access to storage. Explore this reference guide to learn more about how Mellanox key technologies can help improve efficiencies in your vSAN environment. Higher Efficiency RoCE CertifiedWithout Offloads With Mellanox Offloads Efficient Hardware OffloadsA variety of new workloads and technologies areincreasing the load on CPU utilization. Overlay networks protocols, OVS processing, access to storage and others are placing a strain on VMware environments. High performance workloads require intensiveprocessing which can waste CPU cycles, and choke networks. The end result is that application efficiency is limited and virtual environments as a whole become inefficient. Because of these challenges, data center administrators now look to alleviate CPU loads by implementing intelligent network components that can ease CPU strain, increase network bandwidth and enable scale and efficiency in virtual environments.Mellanox interconnects can reduce the burden byoffloading many networking tasks, thereby freeing CPU resources to serve more VMs and process more data. Side-by-side comparison shows over a 70% reduction in CPU resources and a 40% improvement in bandwidth.Reduce CPU OverheadvSphere 6.5, introduced Remote Direct Memory Access over Converged Ethernet (RoCE). RoCE allows direct memory access from one computer to another without involving the operating system or CPU. The transfer of data is offloaded to a RoCE-capable adapter, freeing the CPU from the data transfer process and reducing latencies. For virtual machines a PVRDMA (para-virtualized RDMA) network adapter is used tocommunicate with other virtual machines. Mellanox adapters are certified for both in vSphere.Without Offloads With OffloadsRoCE dramatically accelerates communication between two network endpoints but also requires a switch that is configured for lossless traffic. RoCE v1 operates overlossless layer 2 and RoCE v2 supports layer 2 and layer 3. To ensure a lossless environment, you must be able to control the traffic flows. Mellanox Spectrum switchessupport Priority Flow Control (PFC) and Explicit Congestion Notification (ECN) which enables a global pause across the network to support RDMA. Once RoCE is setup onvSphere close-to-local, predictable latency can be gained from networked storage along with line-rate throughput and linear scalability. This helps to accommodate dynamic, agile data movement between nodes.HPE StoreFabric M-series and Mellanox ConnectX adapter solutions for VMWareProven PerformanceRDMA for vSAN and Ne x t-Gen StorageRDMA (Remote Direct Memory Access) allows two system to connect sub-OS directly to memory without requiring CPU cycles. This enables high bandwidth, increased IOPS, and low latencyconnectivity, which accelerates workloads running on parallel systems better than traditional TCP/IP connectivity.RDMA benefits to vSAN clusters include:•Improved app performance•Improved resync/rebuild/rebalance time •NVMe-oF technology enablement •Better VM consolidation•Improves cloning and vMotion operations times •Faster metadata updates across vSAN hostsMellanox End-to-End vSAN SolutionHyperconvergedReduce CapExHypeconverged deployments, like HPE SimpliVity and HPESynergy, are a demandingenvironment for networkinginterconnects. These consist ofthree software components: compute virtualization, storage virtualization and management, in which all three require an agile and responsive network.Deploying on 25G networks, like offered with Mellanox ConnectX adapters, assists with offload capabilities to optimizeperformance and availability of synchronization and replication ofvirtualized workloads .CapEx Analysis: 10G vs 25G Mellanox adapters and switchesaccelerate VM resources to improveperformance, enhance efficiency and provide high-availability and are a must-have feature for any VMware and hyperconverged environment.

d a t a s he e t / 1What Is Virtual SAN?VMware Virtual SAN is a new software-defined storage tier for VMware vSphere, bringing the benefits of the software-defined data center to storage. By clustering server hard disk and solid state drives (HDDs and SSDs), Virtual SAN creates a flash-optimized, highly resilient shared datastore designed for virtual environments.Based on a hypervisor-converged distributed architecture embedded in the vSphere kernel, Virtual SAN can make optimal data placement and I/O optimizations. Because it sits directly in the I/O data path, the product is able to deliver the highest levels of performance, scalability, and resilience without taxing the CPU with additional overhead.Virtual SAN also differs from other storage products in its policy-based approach to storage management. This management architecture enables administrators to specify storage attributes—such as capacity, performance, and availability—in the form of simple policies on a per-VM basis. These policies, governed by service-level agreements (SLAs), dynamically self-tune and load-balance the system so that each virtual machine has the right level of resources. The system can adapt to ongoing changes in workload conditions to ensure that each virtual machine has the storage resources it needs.Virtual SAN distributed architecture leverages enterprise-grade SSDs for high-performance read/write caching and HDDs for cost-effective data persistence. Using server-side storage, Virtual SAN delivers unmatched price/performance compared to other Virtual Storage Appliances (VSA) or midrange hybrid arrays in themarket today. The Virtual SAN datastore granularly scales up by adding more disks or scales out by adding more hosts, allowing users to configure the system to meet their needs flexibly.Virtual SAN is simple and automates time-consuming manual storage tasks. Not only is Virtual SAN managed through the VMware vSphere® Web Client, but it also integrates with other VMware products such as VMware® vCenter™ Site Recovery Manager™ and VMware vCloud® Automation Center™. This integration makes provisioning and management of storage in virtual environments easy and seamless.Key Features and CapabilitiesHypervisor-converged storage software – Virtual SAN is embedded in the vSphere kernel. This unique characteristic of Virtual SAN makes integration with vSphere seamless and enables best performance and scalability.VMware® Virtual SAN™ is a new software-defined storage tier for VMware vSphere® environments.

For detailed product specifications and system requirements, refer to the vSphere documentation.VM-centric policy-based management – Storage requirements are associated with individual virtual machines or virtual disks in the form of policy statements. Virtual SAN automatically translates these policy statements into system configurations to instantly provision storage with the right SLAs.Server-side read/write caching – Virtual SAN minimizes storage latency by accelerating read/write disk I/O traffic with built-in caching on enterprise-grade server-side flash technology.Built-in failure tolerance – Virtual SAN leverages distributed RAID and cache mirroring to ensure that data is never lost if a disk, host, or network fails.Single pane of glass management with vSphere – Virtual SAN removes the need for training on specialized storage interfaces or the overhead of operating them. Provisioning is now as easy as two clicks.Granular nondisruptive scale-up or scale-out – You can easily and nondisruptively expand the capacity of the Virtual SAN datastore by adding hosts to a cluster or disks to a host.Hardware independence – Virtual SAN can be deployed on hardware from any server manufacturer. This gives you the flexibility to build out customized storage systems in heterogeneous hardware environments.Interoperability with VMware stack – Virtual SAN leverages vSphere snapshots, vSphere clones, VMware vSphere® Data Protection™, and vSphere Replication for data protection, backup, rapid cloning, and disaster-recovery (DR) purposes. Virtual SAN interoperates with vCloud Automation Center and vCenter™ Operations Management Suite™ and can be deployed in conjunction with VMware® Horizon View™ in VDI environments and vCenter Site Recovery Manager in DR environments.BenefitsSimple – Virtual SAN is the first policy-driven storage product that simplifies how storage is provisioned and managed. It gives you a new way to manage storage by automating many of today’s manual tasks. The new model doesn’t involve LUNs or RAID configurations and removes the need for manual adjustments. High performance – By using server-side flash technology, Virtual SAN enables true server-side read/write caching. The solution optimizes the I/O data path to maximize throughput and minimize latency, and because it is embedded in the VMware® ESXi™ kernel, it is a truly unique solution that delivers better performance than a virtual appliance or an external device.。

VMware Virtual SAN 6.1Server disks as central storage for VMware environmentsVirtual SAN (VSAN) is hypervisor-converged storage and clusters server disks and flash to create radically simple, high performance, resilient shared storage designed for virtual machines.At a GlanceVMware® Virtual SAN™ is VMware’s software defined storage solution for Hyper-Converged Infrastructure (HCI).Seamlessly embedded in the hypervisor, Virtual SAN delivers enterprise-ready, high-performance shared storage for VMware vSphere® Virtual Machines. It leverages commodity x86 components that easily scale to drastically lower TCO by up to 50%. Seamless integration with vSphere and the entire VMware stack makes it the simplest storage platform for virtual machines — whether running business-critical applications, virtual desktops or remote server room apps.Key Benefits■ Radically Simple – Deploy with 2-clicks through the standard vSphere Web Client and automate management using storage policies.■ High Performance – Flash accelerated for high IOthroughput and low latency. Deliver up to 7M IOPS with predictable sub-millisecond response time from a single, all-flash cluster.■ Elastic Scalability – Elastically grow storage performance and capacity by adding new nodes or drives withoutdisruption. Linearly scale capacity and performance from 2 to 64 hosts per cluster.■ Lower TCO – Lower storage TCO by up to 50% by deploying standard x86 hardware components for low upfront investment and by reducing operational overhead. ■ Enterprise High Availability – Enable maximum levels of data protection and availability with asynchronous long distance replication and stretched clusters. ■ Advanced Management – Single pane of glass management from vSphere with advanced storage performance monitoring, troubleshooting and capacityTopicsWhat is VMware Virtual SAN?VMware Virtual SAN is VMware’s software-defined storage solution for hyper-converged infrastructures, a software-driven architecture that delivers tightly integrated compute, networking and shared storage from a single, virtualized PRIMERGY server. Virtual SAN delivers high performance, highly resilient shared storage by clusteringserver-attached flash devices and/or hard disks (HDDs). Virtual SAN delivers enterprise-class storage services for virtualized production environments along with predictable scalability and all-flash performance — all at a fraction of the price of traditional, purpose-built storage arrays. Just like vSphere, Virtual SAN provides users the flexibility and control to choose from a wide range of hardware options and easily deploy and manage it for a variety of IT workloads and use cases. Virtual SAN can be configured as all-flash or hybrid storage. Architecture and Performance: Uniquely embedded within the hypervisor kernel, Virtual SAN sits directly in the I/O data path. As a result, Virtual SAN is able to deliver the highest levels of performance without taxing the CPU with overhead or consuming high amounts of memory resources, as compared to other storage virtual appliances that run separately on top of the hypervisor. Virtual SAN can deliver up to 7M IOPS with an all-flash storage architecture or 2.5M IOPS with a hybrid storage architecture.Scalability: Virtual SAN has a distributed architecture that allows for elastic, non-disruptive scaling from 2 to 64 hosts per cluster. Both capacity and performance can be scaled at the same time by adding a new host to the cluster (scale-out); or capacity and performance can be scaled independently by merely adding new drives to existing hosts (scale-up). This “Grow-as-you-Go” model provides linear and granular scaling with affordable investments spread out over time. Management and Integration: Virtual SAN does not require any additional software to be installed—it can be enabled in a few, simple clicks. It is managed from the vSphere Web Client and integrates with the VMware stack including features like vMotion®, HA, Distributed Resource Scheduler™ (DRS) and Fault Tolerance (FT) as well as other VMware products such as VMware Site Recovery Manager™, VMware vRealize™ Automation™ and vRealize Operations™.Automation: VM storage provisioning and storage service levels (e.g. capacity, performance, availability) are automated and controlled through VM-centric policies that can be set or modified on-the-fly. Virtual SAN dynamically self-tunes, adjusting to ongoing changes in Key Features and CapabilitiesKernel embedded– Virtual SAN is built into the vSphere kernel, optimizing the data I/O path to provide the highest levels of performance with minimal impact on CPU and memory resources.All-Flash or hybrid architecture– Virtual SAN can be used in all-flash architecture for extremely high and consistent levels of performance or in a hybrid configuration to balance performance and cost.Expanded enterprise-readiness– support for vSphere Fault Tolerance, asynchronously replicating VMs across sites based on configurable schedules of up to 5 minutes, continuous availability with stretched clusters and major clustering technologies including Oracle RAC and Microsoft MSCS.Granular non-disruptive scale-up or scale-out– Non-disruptively expand the capacity of the Virtual SAN data-store by adding hosts to a cluster (scale-out) to expand capacity and performance or disks to a host (scale-up) to add capacity or performance.Single pane of glass management with vSphere– Virtual SAN removes the need for training on specialized storage interfaces or the overhead of operating them. Provisioning is now as easy as two clicks.VM-centric policy-based management– Virtual SAN uses storage policies, applied on a per-VM basis, to automate provisioning and balancing of storage resources to ensure that each virtual machine gets the specified storage resources and services.Virtual SAN Stretched Cluster– Create a stretched cluster between two geographically separate sites, synchronously replicating data between sites and enabling enterprise-level availability where an entire site failure can be tolerated, with no data loss and near zero downtime. Advanced management– Virtual SAN Management Pack for vRealize Operations delivers a comprehensive set of features to help manage Virtual SAN, including global visibility across multiple clusters, health monitoring with proactive notifications, performance monitoring and capacity monitoring and planning. The Health Check Plug-in complements the management pack for additional monitoring including HCL compatibility check and real-time diagnostics.Server-side read/write caching– Virtual SAN minimizes storage latency by accelerating read/write disk I/O traffic with built-in caching on server-side flash devices.Built-in failure tolerance– Virtual SAN leverages distributed RAID and cache mirroring to ensure that data is never lost if a disk, host, network or rack fails.Deployment OptionsCertified Hardware: Control your hardware infrastructure by choosing from certified components on the hardware compatibility list, see /resources/compatibility/search.php?deviceCat egory=vsanPRIMEFLEX for VMware VSAN: Select a pre-configured hardware solution that is certified to run Virtual SAN.

Al-though VDI was used to benchmark the perfor-mance of this Virtual SAN implementation, anyapplication supported by ESXi 5.5 can be used.VSAN is VMware’s hypervisor-converged storagesoftware that creates a shared datastore acrossSSDs and HDDs using multiple x86 server hosts.T o measure VDI performance, the Login VSI work-load generator software tool was used to test theperformance when using Horizon View. VDI per-formance is measured as the number of virtualdesktops that can be hosted while delivering auser experience equal to or better than a physicaldesktop including consistent, fast response timesand a short boot time. Supporting more desktopsper server reduces CAPEX and OPEX requirements.Benefits of Virtual SANData storage in VMware ESXenvironments has historicallybeen supported using NAS-or SAN-connected sharedstorage from vendors such asEMC, Netapp, and HDS. Theseproducts often have consider-able CAPEX requirements andbecause they need specially-trained personnel to supportthem, OPEX increases as well.VSAN eliminates the needfor NAS- or SAN-connectedshared storage by using SSDsand HDDs attached locally tothe servers in the cluster. Aminimum of three servers arerequired in order to survive a server failure. Infor-mation is protected from storage device failure byreplicating data on multiple servers. A dedicatednetwork connection between the servers provideslow latency storage transactions.SSDs Boost Virtual SAN PerformanceApplication performance is often constrainedby storage. Flash-based SSDs reduce delays(latency) when reading or writing data to harddrives, thereby boosting performance.READ Caching: By caching commonly accesseddata in SSDs READ latency is significantlyreduced because it is faster to retrieve datadirectly from the cache than from slow, spin-ning HDDs. Because DRS1 may cause VMs tomove occasionally from one server to another,VSAN does not attempt to store a VM’s dataon a SSD connected to the server that hoststhe VM. This means many READ transactionsmay need to traverse the network, so highbandwidth and low latency is critical.Implementing VMware’s Virtual SAN™ with Micron SSDs and the Mellanox Interconnect SolutionFigure 1. Virtual SAN1 VMware’s Dynamic Resource Scheduling performs application load balancing every 5 minutes.WRITE Buffering: VSAN temporarily buffers all WRITEsin SSDs to significantly reduce latency. T o protectagainst SSD or server failure, this data is also stored on a SSD located on different server. At regular intervals, the WRITE data in the SSDs are de-staged to HDDs. Because Flash is non-volatile, data that has not been de-staged is retained during a power loss. In the event of a server failure, the copy of the buffered or de-staged data on the other server ensures that no data loss will occur.Dedicated Network Enables Low Latency for VSANMost READ and all WRITE transactions must traverse over a network. VSAN does not try to cache data that is local to the application because it results in poor balancing of SSD utilization across the cluster. Because caching is distributed across multiple servers, a dedicated network is required to lower contention for LAN resources. For data redundancy and to enable high availability, data is written to HDDs located on separate servers. Since two traverses across the network are typically required for a READ and one for a WRITE, the latency of the LAN must be sub-millisecond. VMware recommends at least a 10GbE connection.VSAN-Approved SSD ProductsVMware has a compatibility guide specifically listing I/O controllers, SSDs, and HDDs approved for implementing VSAN. Micron’s P320h and P420m PCIe HHHL SSD cards are listed 2 in the compatibility list.Tested ConfigurationThree servers, each with dual Intel Xeon E5-2680 v2 pro-cessors and 384GB of memory, were used for this test. Each server included one disk group consisting of one SSD and six HDDs. Western Digital 1.2TB 10K rpm SAS hard drives were connected using an LSI 9207-8i host bus adapter set to a queue depth of 600. A 1.4TB Micron P420m PCIe card was used for the SSD. A dedicatedstorage network supporting VSAN used Mellanox’s end-to-end 10GbE interconnect solution, including their SX1012 twelve-port 10GbE switch, ConnectX ®-3 10GbE NICs and copper interconnect cables.On the software side, ESXi 5.5.0 Build 1623387 and Ho-rizon View 5.3.2 Build 1887719 were used. Within the desktop sessions, Windows 7 64-bit was used. Each per-sistent desktop used 2GB of memory and one vCPU. VDI performance was measured as the number of virtual desk-tops that could be hosted while delivering a user experi-ence equal to or better than a physical desktop.ResultsVersion 4.1.0.757 of the Login VSI load simulator was used for testing. This benchmark creates the workload representative of an office worker using Microsoft Office applications. The number of desktop sessions is steadily in-creased until a maximum is reached, in this case 450 ses-sions. Increasing the number of sessions raises the load on the servers and the VSAN-connected storage, which causes response times to lengthen. Based on minimum, average, and maximum response times, the benchmark software will calculate VSImax, which is their recommen-dation for the maximum number of desktops that can be supported. The following figure shows that using the three-server configuration, up to 356 desktops can be supported.Figure 2.

All other trademarks are property of their respective owners.15-4175SB Rev1.0Other critical factors in VDI environments are the times required to boot, deploy, and recompose desktops. Boot is when an office worker arrives at work and wants to access their desktop. Deploy is the creation of a desktop session, and recompose is the update of an existing session. An update may be required after a patch release has been dis-tributed. For this test, 450 desktops were simultaneously booted, deployed, and recomposed.• Boot: 0.7 seconds/desktop • Deployment: 7.5 seconds/desktop • Recompose: 9.2 seconds/desktopConclusionSoftware-defined storage appears to be a viable alternative to SAN or NAS storage from our experience using VSAN. Using directly-attached SSDs and HDDs can provide supe-rior performance by bypassing the need for shared storage. The VSAN implementation provides the fault tolerance and high availability necessary for enterprise environments that has historically has been the limitation of DAS.Read caching and write buffering using the Micron P420mPCIe SSD sufficiently masks the latency limitations of HDDs, allowing VMs to run at high performances. Since VMs frequently move between servers for load balancing, there is no guarantee that SSDs that are local to the VM will have cached data. The Mellanox interconnect provides low latencies whenever accessing data between servers is necessary.T o evaluate the Micron and Mellanox hardware supporting VSAN, VMware’s Horizon View virtual desktop application was implemented. Using the Login VSI workload simu-lator, 356 desktops were hosted across three servers. This number is comparable to what a SAN- or NAS-connected shared storage implementation can support, but at a frac-tion of the cost.About Login VSILogin Virtual Session Indexer (Login VSI) is a software tool that simulates realistic user workloads for Horizon View and other major desktop implementations. It is an industry stan-dard for measuring the VDI performance that a softwareand hardware implementation can support.Figure 3. VSAN Results。
VMware vSphere 网络概述VMware vSphere 网络：概述”要想详细地了解虚拟网络组件，必须要了解 vSphere 数据中心的体系结构。
典型的 vSphere 数据中心包含多种基本物理构建块，例如 x86 计算服务器、存储网络和阵列、IP 网络、管理服务器和桌面客户端。
计算服务器是指在裸机上运行 VMware ESXi ™的业界标准 x86 服务器。
虚拟机驻留在 ESXi 服务器上。
虚拟机所需的所有资源均由ESXi 服务器提供。
每台计算服务器在虚拟环境中均称为独立主机。
可将具有相似配置的多个 x86 服务器组合在一起并连接到同一网络和存储子系统，从而在虚拟环境中形成一个资源池。
在光纤通道存储区域网络（SAN 阵列）、Internet 小型计算机系统接口（iSCSI SAN 阵列），以及网络连接阵列（NAS 阵列）等应用广泛的存储技术的支持下，vSphere 可满足不同数据中心的存储需求。
通过存储区域网络在各组服务器之间共享存储阵列，这使 IT 部门可以将存储资源汇聚成资源池，从而更灵活地为虚拟机调配存储资源。
每台计算服务器可以拥有多个千兆位以太网网卡，为整个数据中心提供高带宽且可靠的网络连接。
借助 VMware vCenter™可以方便地对数据中心进行单点控制。
它在 Windows 2003 和2008 Server 64 位版操作系统上运行，可提供许多基本的数据中心服务，例如访问控制、性能监视和配置。
vCenter Server 可将各个计算服务器的资源整合起来，以供整个数据中心内的所有虚拟机共享。
它通过以下方式做到这一点：根据系统管理员设定的策略，管理分配给计算服务器的虚拟机，以及分配给特定计算服务器内虚拟机的资源。
即使无法访问 vCenter Server（例如，网络断开），计算服务器也能继续工作。
计算服务器可分别单独管理，这些计算服务器将基于上一次设置的资源分配策略，继续运行分配给它们的虚拟机。
