SAN Switches

BR788674 — Thu, 22 Apr 2004 10:40:16 GMT

I currently have two HSG80's and and EVA3000 setup with 4 SAN Switch 16's ( two of which are EL models). I have a requirement to add more ports to this setup but I understand that more switches will require the purchase of upgrade licences for the 2 EL's.

Is it possible to zone to avoid this restriction? My thinking was to put the HSG's into 2 switches in one zone, the EVA into 2 switches in another and The backup libraries into a 5th switch in both.

I suspect the answer to this is no but would like to avoid having to pay for new switches and licences at the same time.

Dan,
you cannot use zoning to work around license restrictions. The suggestion from HP is to use always use zoning when an EVA is used to create a separate management zone for the EVA and the SMA anyway.

What type of EL switch is this? 212776-B21? As far as I can tell from the quickspecs this one has a full fabric license.

If this is the SANswitch 2/16-EL (283056-B21) it looks like it has a 4-switch fabric license in the base model.

I don't know what your current fabric looks like - it sounds like all 4 switches are in one fabric, but the only other way I see is to split and build two separate fabrics if you server connectivity allows for this?

How are they connected? Dual- or single-path?

Hi,

Didn't think so but I thought I'd check. Yes, they are SANswitch 2/16-EL (283056-B21) with the 4 switch limit. I unfortunately can't split into two fabrics because of the backups, so will have to get them to stump up the cash for the upgrade licences.

Thanks for you help.
