V7000 Storwize Upgrade For Lenovo

The firmware update process from Lenovo:

During the automatic update process, each node in a system is updated one at a time, and the new code is staged on the nodes. While each node restarts, there might be some degradation in the maximum I/O rate that can be sustained by the system. After all the nodes in the system are successfully restarted with the new code level, the new level is automatically committed.

During an automatic code update, each node of a working pair is updated sequentially. The node that is being updated is temporarily unavailable and all I/O operations to that node fail. As a result, the I/O error counts increase and the failed I/O operations are directed to the partner node of the working pair. Applications do not see any I/O failures. When new nodes are added to the system, the update package is automatically downloaded to the new nodes from the Lenovo Storage V7000 system.

The update can normally be done concurrently with normal user I/O operations. However, performance might be impacted. If any restrictions apply to the operations that can be done during the update, these restrictions are documented on the product website that you use to download the update packages. During the update procedure, most of the configuration commands are not available.Only the following commands are operational from the time the update process starts to the time that the new code level is committed, or until the process is backed out:

• All information commands
• The rmnodecanister command

To determine when your update process completes, you are notified through the management GUI. If you are using the command-line interface, issue the lsupdate command to display the status of the update.

Because of the operational limitations that occur during the update process, the code update is a user task. If you have problems with an update, however, contact your support center. Do not try to troubleshoot update problems without technical assistance. For further directions, see the topic about how to get information, help, and technical assistance.

Also available is an optional cache upgrade to 128 GB or 256 GB per system (64 GB or 128 GB per node canister). Standard is 1 Gb iSCSI connectivity, with an option for 8 Gb (Model 524 only) or 16 Gb Fibre Channel (FC), 10 Gb iSCSI or Fibre Channel over Ethernet (FCoE), or 25 Gb iSCSI (Model HC1 only) connectivity.

Storwize V7000 offers both Large Form Factor (LFF) and Small Form Factor (SFF) 12 Gb SAS storage expansion units. LFF expansion unit supports up to 12 3.5-inch drives, while the SFF expansion unit supports up to 24 2.5-inch drives. High-performance disk drives, high-capacity nearline disk drives, and flash (solid state) drives are supported. Drives of the same form factor can be intermixed within an enclosure, and LFF and SFF expansion enclosures can be intermixed within a Storwize V7000 system.

A Storwize V7000 system scales up to 504 drives with the attachment of up to 20 Storwize V7000 expansion units. The Storwize V7000 Storage Controller Unit is shown in the following figure.
