The SMB file system on PowerStore supports SMB versions up to SMB3.1.1. A single NAS and file-system instance can support both SMB and NFS simultaneously. This support allows for creating file shares that are based on user type or operating environment. PowerStore arrays support multiple file systems for flexibility, security, and availability. Once the upgrade is complete, NAS servers should be moved back to their preferred nodes. This movement should be performed outside of business hours if the IO or CPU demand on the appliance is high during the business day. NAS servers are automatically moved to the peer node during upgrades. A maintenance event should be scheduled if possible but is not required. If a node failure does occur at some point, a maintenance event should be scheduled to move the NAS instance back to the preferred node.įailover generally completes within 30 s to avoid host timeouts. However, there are some points to be aware of.įailback is a manual process. If there is a single-node failure or an in-place upgrade, the service is designed to fail over to the other node automatically. NAS servers are highly available by design. This use automates data redirection for greater control and centralized management. This tool allows setting dynamic rules to place data based on user-defined criteria. The type of data determines the best method of balancing the load.įor user profiles, a tool like VMware Dynamic Environment Manager (DEM) can be used to balance the data across multiple file systems. The load can then be split between the two instances. Enforced isolation helps increase security and stability.īecause a NAS instance runs on a single node to get maximum performance, a minimum of two NAS servers is recommended. Each NAS server has its own independent configuration (for example, DNS, LDAP, NIS, interfaces, protocols, and so forth).īecause each NAS instance is isolated, multiple environments can share a single system. NAS servers are logically separated from each other.Ĭlients of one NAS server do not have access to data on other NAS servers. This support has multiple benefits, including the following: A key feature of PowerStore is the ability to support multiple NAS servers on the same array.
