    It is recommended that this network be isolated from the LAN or client network. PowerVault NX3500 Architecture The PowerVault NX3500 combined with MD3xxxi provides you with a unified storage solution (see Figure 1-1). This solution provides you with access to both block and file storage (see Figure 1-2).

PowerVault NX3500 Views You can access the PowerVault NX3500 as a client or an administrator depending on the access privileges you have. NOTE: It is recommended that you do not attempt to log on to both the CLI and NAS Manager at the same time.
  • Page 24 Define NAS host in MD iSCSI array Client View To the client, the PowerVault NX3500 presents itself as a single file-server with a single file system, IP address, and name. The PowerVault NX3500's global file system serves all users concurrently without performance constraints.
  • Page 25: System Components

    LAN or client network NAS Controller Pair The PowerVault NX3500 clustered NAS solution consists of two NAS controllers configured as a pair. This redundant configuration ensures that there is no single point of failure. The controllers handle load balancing of client connections, manage read-write operations, perform caching, and interface with servers and workstations.
  • Page 26: Powervault Md Storage

    You can view the BPS events on the NAS Manager. SAN Network The SAN network is a critical part of the PowerVault NX3500 solution. The controller pair that resides on the SAN network communicates to the storage subsystem using the iSCSI protocol. The PowerVault NX3500 communicates on the SANa and SANb networks, rendering a high availability (HA) design.
  • Page 27: Internal Network A

    After the initial configuration, a virtual IP (VIP) address connects the PowerVault NX3500 to the client or LAN network. The VIP address allows clients to access the PowerVault NX3500 as a single entity, thereby providing access to the file system. It enables the PowerVault NX3500 to perform load balancing between controllers, and ensures that the service continues even if a controller fails.

  • Page 93: Usage Considerations

    Usage Considerations Choosing to define multiple NAS volumes enables administrators to apply different management policies such as, Backup, Snapshots, Quotas, and Security Style to their data. Without regard to the strategy used, the storage is managed as one storage pool and free space can easily be migrated between NAS volumes, by changing the NAS volume's allocated space.
  • Page 94: Solution 1

    • Quotas—Quotas are also defined per NAS volume. Different quota policies can be applied to different NAS volumes, allowing the administrator to focus on managing quotas when it is appropriate. Some of the usage examples are copy operations, list operations, and move operations.
  • Page 95: Solution 2

    This solution provides the following advantages: • It is logically easy to manage the NAS volumes. • The NAS volumes are created to match the exact needs of the department. The disadvantage of this option is that the NAS volumes become difficult to manage if the number of departments in the organization increases.
  • Page 96: Adding A Nas Volume

    2 Change the parameters as required and click Save Changes. NOTE: If you change the allocated space for the NAS volume, the new allocation is bound by its used space (minimum) and the available space in Dell PowerVault NX3500 (maximum).
