Deep dive podcast with StoreVirtual VSA team

This past week, as a follow up to the HP StoreVirtual VSA announcement we made, I had a live podcast on Thursday.  It was a good mix of questions from the audience (I took questions via TalkShoe chat).  Brad Katz is the HP StoreVirtual VSA product manager and joined Kate Davis (a regular guest blogger here on ATSB).  Here's roughly what we covered:

  1. Kate gave an overview what's new with StoreVirtual VSA and LeftHand OS v 11.0
  2. Brad filled in a few technical details about paravirtualized SCSI adapter (PV SCSI Adapter), and downloading updates to LeftHand OS
  3. From there, we spent a majority of the time talking about the new sub-LUN tiering with StoreVirtual VSA, what we call Adaptive Optimization.  Brad talks about how it works, the architecture of AO, and talking about the difference between sub-LUN tiering and using flash cache.
  4. Kate and Brad talked about the new licensing for VSA (3 capacity points)
  5. Brad answered a question about UNMAP - we don't have support for it in 11.0 but Brad gave some color to this.
  6. Brad gave some details about how many nodes can be supported in a VSA cluster and management group.
  7. We hit OpenStack and using it to manage HP StoreVirtual and Brad wrapped things up by talking about application aware snapshots with StoreVirtual.

Here's the podcast:

One of the questions we got were support for 10GbE - and during the live call, Brad didn't have the details for what HBAs/CNAs will support 10GbE so here's what Brad told me after the call: HP NC553i/NC553m 10Gb 2-port FlexFabric CNA and  554FLB Adapter.  These are the ProLiant G7 and Gen8 LOMs that ship with our blades.

Hi Calvin,


The AO announcment is great news. I listened to the podcast with Brad and I had a question regarding how to implement tiered storage for AO. 


If I have several x86 servers with physical RAID-6 hosting my existing VSAs, would I need to create a separate disk group with SSD to use AO? If I already have smart-cache controllers with SSD would trying to use AO be a moot point?

How often does AO move data? What are the scan and move windows? And can they be changed?

Hey Calvin, any word on why the upgrade path through CMC has been pushed back so many times?  I know nobody wants a bad release, but some communication on the continued date changes would be appreciated.

Hey @oikjn -

You're question suggests that you know we have made LeftHand OS 11.0 available for both VSA and it's also now shipping on new appliances based on ProLiant Gen8 servers.  Just as the team was putting the version on the web for upgrade via the CMC, they found an issue with G2 - based appliances.  They believe they've fixed it and are testing that over the holiday shutdown.  We hope to deliver it soon after the new year. 


Happy Christmas!
