MSA500 migration path to SAN

giovanni_25 — Sun, 10 Aug 2008 21:32:36 GMT

Hello,

I read that it's possible to replace an MSA500 G2 controller with an MSA1000 controller (218231-B22 it seems the part number).

The problem is that MSA1000 controller should be an Ultra3 instead of an Ultra320. Is there any solution to upgrade my customer MSA500 to a SAN FC based Hardware keeping the Ultra320 Speed and gaining the Virtual Infrastructure - ESX3i compatibility?

Wich is the path to do it, if possible!?

Thanks in advance.

Bye,
Giovanni

I read the document before opening this thread.

The problem is not the possibility to do the migration but if there is a way to migrate the MSA500 G2 to another MSA???? that works at Ultra320 Speed: is there any firmware upgrade for MSA1000 that can bring this controller to Ultra320 or is there any MSA500G2 compatible controller that works at that speed?

Thanks Again.

Ciao,
Giovanni

Hi,
a) the MSA 1000 is fibre only, therefore the part of the migration procedure is the controller replacement

b) but you can replace the server controller to the Ultra320 Smart Array 6i Plus Controller

Could you please have a look to this:

I mean, it seams the MSA1000 controller BUS speed is Ultra3 (or Ultra160)... I'm referring to that speed. Is it possible to improve that speed? Changing the server controllers I don't beleave that I could achieve this.

Thanks again.

Now I see :-), but unfortunately my reply is only the repetition of the known info:
MSA1000 provides Ultra3 SCSI connections to the hard drives and uses the HP Universal 1â Ultra2, Ultra3, and/or Ultra320 drives.

In an active/active configuration of a dual controller MSA1000 does throughput reach MSA500 U320 single controller troughput?

This could be enough for my new customer to implement something not worst than actual single controller MSA500: comparable performance and better avialability!?

Am I right in this analisys?

Thanks (I hope last time for this topic!),

Giovanni

Hi,
in active/passive only one from the 2 installed controllers can access to the MSA configured volumes, the other is the pure standby

in active/active both controllers can access to the MSA configured volumes
