Here’s a really nice chart that I ran across in the online release notes of SAN/iQ v8.5, which will help explain the differences between all of the SAN/iQ Network Raid levels, especially since there were some name changes to the levels between 8.1 and 8.5.
Notice the big difference between the Raid 10 levels and the Raid 5 & Raid 6 levels are Raid 5 & 6 are stripes with parity based, while all of the Raid-10 levels are stripes with mirror based.
Hope it helps and any questions, feel free to post a comment! ;-)
I found this “patch” link while actually looking for something else. Here’s a “patch” file which will perform the upgrade to SAN/iQ version 8.5 on your HP Lefthand nodes from previous versions of SAN/iQ, starting at SAN/iQ v7.00.
This should save you the “rig-a-ma-roll” of trying to download the upgrade file through the HP website..
Also of note, here’s our other post related to getting SAN/iQ 8.5:
When performing an upgrade to SAN/iQ v8.5, I noticed that the management group version wasn’t being updated to 8.5 and was still at 8.0 even after upgrading all nodes in the management group. I also noticed that the Network RAID 5 feature wasn’t showing up in the list for the volumes (either on new volumes or editing existing volumes).
The reason behind this was because the management group was in a remote IP copy relationship with another “DR” management group, which was not upgraded to 8.5 yet. Once I upgraded the nodes on the DR management group, everything upgraded like it should and the new Network RAID options were available.
Note: This behaviour is shown in the upgrade guide too, page 12:
• When upgrading from version 7.x to release 8.5, the management group version will not move
to release 8.5 until all storage nodes in the management group (and in the remote management
group if a Remote Copy relationship exists) are upgraded to release 8.5 SAN/iQ.
• When upgrading from version 7.x to release 8.5, the upgrade process validates the hardware
identity of all of the storage nodes in the management group. If this validation fails for any reason,
the management group version will not be upgraded to 8.5. For example, if a management group
has a mix of platforms, some of which are unsupported by a software release; then only the supported
platforms get upgraded successfully, the management group version will not be upgraded
if the unsupported platforms remain in that management group.
As of the 29th of March, SAN/iQ 8.5 is available for download – here are the details (from HP)
SANIQ version 8.5 allows customers to:
1 Reclaim additional capacity with network RAID 5 and 6 (up to 50% additional capacity utilization)
2 Simplify business continuity with application integrated snaps for scheduled local and remote sites
3 Analyze their existing configuration to ensure adherence to industry best practices
4 Support external FC/iSCSI/SAS via VSA, allowing customers to repurpose 3rd party storage

** Well, I thought this was too good while it lasted. This link no longer works. It looks like you’ll have to use the ITRC link above in order to get the software. If this changes, we’ll let you know!**
Update 5-28-10: Check out this post where you can get a patch file that performs the upgrade, right off the HP site in the post:
Thanks to vstorage.wordpress.com for the direct download link and info on this post! They also have a great post on the new features, here:
The Lewan LPS team will hope to be doing some performance testing with the new Network Raid 5 feature here in the near future! Stay tuned!
Great article pointing out the VMware networking differences between Flex-10 and UCS QoS. Of course HP is getting ready to make some more changes to their Flex-10 (Flex Fabric I think it is called) so stay tuned.
Great comprehensive article on HP Virtual Connect Flex 10…video and all!
