Add new StoreVirtual Node to Existing Gen2 Cluster

Hello,

 

we´ve an existing Cluster with 5 P4300 Gen2 Node with 8 x 450 15 SAS drives.

Now we need to add an other node. Can we mix the Gen2 Nodes with the new StoreVirtual Models?

 

Thanks for your help

 

Martin

yes...

 

just make sure you get one that is similar for performance/capacity as your cluster will have as much space available as the smallest node and be as fast as the slowest node.  I think there is a conversion chart somewhere to show which gen2 goes w/ which gen3, but ask your VAR or HP.

In addition, the cluster will assume the "lowest common denominator" LeftHand OS version - so even though you add new nodes with the latest OS, those will revert to whatever is the oldest OS version in the existing cluster.

HP - is that per cluster or per management group?

Hi,

 

That is per cluster...

Re: Add new StoreVirtual Node to Existing Gen2 Cluster

I have the portfolio transition table here with me but it is hard top paste some pictures here in this forum...

I can tell you that the replacement for the P4300 G2 with 8 x 450GB will be the StoreVirtual 4330 450 GB SAS Storage...

Product number is B7E17A

Re: Add new StoreVirtual Node to Existing Gen2 Cluster

I was just talking to an HP StoreVirtual expert and what he told me was that LeftHand OS features are determined at the management group layer. 

Bart - I know you are hands on with StoreVirtual all the time.  I'm not clear if there's an option to do this at a cluster or management group but sounds like my HP product experts say management group is the way to go.

OK mixing up some things here...

 

OS features set and software upgrades are indeed determined at management group level...

 

What I ment is the performance of mixing generations of nodes and the performance of it... This is at cluster level.

That is also the reason why it is best to create multiple clusters with preferably the same type of nodes per cluster...

For instance a cluster with midline drives for archiving and another cluster with SAS drives for performance...

We were also told that the difference between OS versions may not be too large. E.g. you cannot add nodes running LefthandOS 11.0 to a cluster running SAN/iQ 9.5.

What about Automatic Online Upgrades? Will be able to detect that 12.6 can be installed only on 4530 and 12.5 can be installed on P4500G2? I need to upgrade a mixed management group and I don't know if I have to use  Automatic Online Upgrades or to use Manual Upgrades.

Thanks.

In the CMC Help menu, select Preferences > Upgrades. Select the Advanced Upgrade Selection Mode. Click Ok.

The Upgrades page will now give you a list of options when you click Continue. Select LHOS 12.5 to upgrade any G2 units to 12.5.  Do not try to upgrade G2 units to 12.6; it is unsupported.

New StoreVirtual units are delivered with 12.6 installed. StoreVirtual 4x30 units running 12.6 are compatible with G2 units running 12.5 in the same management group.
