VMware存储DRS(SDRS)
SDR可以通过分析可用数据标准的容量并将新的虚拟机放置在具有所需的可用容量的数据存储中,从而帮助简化数据存储(LUNS / NFS MAINTS)的管理。这称为“初始位置”。SDR还允许管理员创建规则(“亲和力”和“抗亲和力”)为了确保出于性能 /容量原因确定应将哪些VM放在一起或分开,并最终监视I / O指标,并将VMS迁移到存在争夺或容量约束的不同数据存储中。
由于建议在Nutanix环境中拥有一个大型NFS数据存储,因此,初始位置(SDRS帮助解决)的问题被本地消除,因为所有虚拟机,无论性能或容量要求如何并且应该放入一个NFS数据存储中跨越整个Nutanix群集(并且可能是多个vSphere簇),并可以访问Nutanix存储池中的所有可用存储空间。
因此,vSphere管理员或配置工具可以简单地将所有虚拟机放入单个NFS数据存储中,从而消除对“初始位置”功能的需求。
接下来让我们讨论“亲和力”和“反亲和力”规则这有助于优化VM性能。当Nutanix在每个节点上运行虚拟存储控制器(或CVM)时,在不同的ESXI主机上运行的虚拟机可以访问其自己的存储控制器。
结果,不需要“亲和力”和“抗亲和力”SDRS层处的规则,因为可以在Vsphere DRS层上配置这些规则。所有运行业务关键应用程序(VBCA)的所有虚拟机都应配置具有“主机上的虚拟机”规则,并具有“应在此主机上运行”的“应在此主机上运行”,就像您在集中共享存储上的传统vsphere环境中所配置的那样。
这样可以确保虚拟机不会通过DRS自动移动,除非有需要进行VMotion的HA或维护事件。
在Nutanix环境中,这些规则的额外优势是VBCAS可以访问同一ESXI主机上的虚拟存储控制器,从而消除了通过存储区域网络(FC或IP)访问传统的集中存储的延迟,并通过数据提高性能以及数据Locality&由Nutanix本地缓解“嘈杂的邻居”问题。
接下来我们可以谈论SDRS的基于I/O度量的负载平衡使用一个I/O喷油器测试数据存储的性能和“I/O等待时间阈值“确定是否应重新定位虚拟机。
由于Nutanix围绕以VM为中心的模型而不是每个LUN或数据存储模型设计,因此测试数据存储的性能不再相关,因为其性能可能会根据单个节点的工作量而改变。相反,Nutanix建议在计算层使用较高I/O的VBCA使用DRS抗亲和力规则,以在整个群集上分开此工作负载,以确保最佳的计算和存储性能。
基于空间利用率的负载平衡仅在配置多个数据存储的情况下与每个存储量有限的存储空间相关。在Nutanix世界中,一个数据存储可以访问存储池中的所有可用存储空间,从而消除了基于空间利用率和容量管理周围相关的复杂性加载平衡的要求。
这也确保了可用容量的最佳利用,即:没有浪费的存储筒仓!
最后,sdrs呢“数据存储模式”?
同样,由于Nutanix有一个大数据存储,该数据存储在集群中的所有Nutanix节点都积极服务,如果您需要从集群中删除节点,则该操作由Nutanix分布式文件系统(NDFS)在后台处理,完全透明到vSphere群集。
该过程很简单,将ESXI主机置于维护模式中,所有VM都会自动通过VMotion撤离,然后关闭主机。然后,随着删除节点的工作分布在群集中的所有节点上,可以将Nutanix节点从群集中删除,并且对群集的影响最小。
结果,尽管SDR是减轻传统SAN/NAS环境中的存储容量和性能挑战的重要功能,但在Nutanix环境中并不需要SDR或优势。
存储DRS的建议配置如下;
\n
\nSDRS helps simplify management of Datastores (LUNs \/ NFS Mounts) by analyzing the available datastores capacity and placing new virtual machines in datastores with the required available capacity. This is called \"Initial Placement\". SDRS also allows administrators to create rules (\"Affinity\" & \"Anti-Affinity\")<\/b> to ensure specific what VMs should be kept together or apart for performance \/ capacity reasons and finally, monitor I\/O metrics and relocate VMs to different datastores where contention or capacity constraints exist.
\n
\nAs it is recommended to have one Large NFS Datastore in a Nutanix environment, the issue of initial placement (which SDRS helps resolve) is natively eliminated as all Virtual machines, regardless of performance or capacity requirements can and should be placed into one NFS Datastore which spans the entire Nutanix Cluster (and potentially multiple vSphere Clusters) and has access to all the available storage in the Nutanix Storage Pool.
\n
\nSo the vSphere administrator, or provisioning tool can simply place all Virtual machines into a single NFS Datastore, thus eliminating the requirement for the \"Initial Placement\" feature.
\n
\nNext lets discuss, \"Affinity\" & \"Anti-Affinity\" Rules<\/b> which help optimize VM performance. As Nutanix runs a Virtual storage Controller (or CVM) on every node, Virtual machines running on different ESXi hosts get access to their own Storage controller.
\n
\nAs a result, there is no need for \"Affinity\" & \"Anti-Affinity\"<\/b> Rules at the SDRS layer, as these can be configured at the vSphere DRS layer. All Virtual machines running Business critical applications (vBCAs) with high I\/O requirements should be configured with a \"Virtual Machines to Hosts\" rule with \"Should run on this host\" configured as you would in a traditional vSphere environment on centralized shared storage.
\n
\nThis ensures the Virtual machine does not move around automatically via DRS unless there is a HA or Maintenance event which necessitates a vMotion.
\n
\nThe added advantage of these rules in the Nutanix environment is the vBCAs have access to a virtual storage controller on the same ESXi host, thus eliminating the latency of accessing traditional centralized storage over a Storage Area Network (FC or IP) & improved performance with Data Locality & by Nutanix natively mitigating against the \"Noisy Neighbor\" issue.
\n
\nNext we can talk about SDRS's Load Balancing based on the I\/O Metric<\/b> which uses an I\/O injector<\/b> to test the performance of a Datastore and the \"I\/O latency threshold<\/b>\" to determine if Virtual machines should be relocated.
\n
\nAs Nutanix is designed around a VM centric model, as opposed to a per LUN or Datastore model, testing the performance of a Datastore is no longer relevant as its performance may change depending on the workload of a single node. Instead Nutanix recommends to use DRS anti-affinity rules for vBCAs with high I\/O at the compute layer, to separate this workloads across the cluster to ensure both optimal compute and storage performance.
\n
\nLoad Balancing based on Space Utilization is only relevant where multiple Datastores are configured, each with a finite amount of storage. In the Nutanix world, one Datastore has access to ALL available storage within the Storage Pool thus eliminating the requirement to load balance based on Space utilization and the associated complexity around capacity management.
\n
\nThis also ensures optimal utilization of available capacity, ie: No silos of wasted storage!
\nFinally, what about SDRS \"Datastore Maintenance mode\"? <\/b>
\n
\nAgain as Nutanix has one large Datastore which is actively services by all Nutanix nodes in the cluster, in the event you need to remove a node from the cluster, this operation is handled in the background by the Nutanix Distributed File System (NDFS) completely transparent to the vSphere cluster.
\n
\nThe process is simple, Place the ESXi host into maintenance mode, all VMs are automatically evacuated by vMotion, then shutdown the host. Then the Nutanix node can be removed from the cluster without downtime and with minimal impact to the cluster as the work of removing the node is distributed across all nodes in the cluster.
\n
\nAs a result, while SDRS is a great feature for mitigating the storage capacity and performance challenges in traditional SAN\/NAS environment, SDRS is not required or advantagous in a Nutanix environment.
\n
\nThe Recommended configuration for Storage DRS is as follows;
