do you have dual controllers?

CHI-LTDAuthor Commented:
Yes it will have dual controllers.

Cheers hancock, very useful.  My other concern is the SAN config side of things....

EvertGCommented:
is pretty simple to configure. Just remember that one diskgroup only can be handled by one controllor. So depending on the amount of disks and space needs you can split it between the controllors. For the rest read the guide well about failover configuration. (meaning ip adressing and such.)

Have you logged into the Web GUI yet?

Decided what RAID and Spares you are going to use and create?

was planning on having one volume/array setup.

are these sans clever enough to hot add disks to LUNs/volumes or are they the same setup as a typical server RAID i.e. you would only add the disk as an independent disk?

not logged in as not bought it yet!

Yes you can extend but they are not the fastest one in that part.

CHI-LTDAuthor Commented:
fastest in terms of adding the disk or in terms of after the disk has been added (extended data)?

Extending an ARRAY on a P2000 can take weeks or days to complete.

You add all your disks into a vdisk, and select spares and RAID type.

You cannot mix SAS and SATA disks, so you would need to RAID types.

and then you create Volumes in the vdisk, from the total usable storage available, these are easily expandable, in and instant, and then Expand/Increase on the fly in vSphere.

BUT make sure you get the initial volume correct. because later expansion, takes a while.

So the vdisk is the total array, and volumes are the LUNs which you present to the host ESX servers.

So make sure you configure the correct vdisk with spares to start.

ok cool.

In terms of connectivity of the 1gb ethernet ports on the SAN, i see a lot of info showing use of different ip address ranges.  i.e. host = 192.168.1.10 and san iscsi ip = 192.168.10.10 or even a different class ie. 10.*.*.*.
Does it have to be configured this way?

The SAN will have 2 controllers with 4x ports and the 2 hosts will have 4x ethernet ports also.

Can i setup as:

host 1 - nic0&1 = 192.168.1.10
host 1 - nic2&3 = 192.168.1.11

host 2 - nic0&1 = 192.168.1.12
host 2 - nic2&3 = 192.168.1.13

SAN ctrlr 1 - nic 0&1 = 192.168.1.101
SAN ctrlr 1 - nic 2&3 = 192.168.1.111

SAN ctrlr 2 - nic 0&1 = 192.168.1.112
SAN ctrlr 2 - nic 2&3 = 192.168.1.113

Then ethernet leads load balanced over 2x switches and 2x hosts?

Yes, you may want to look at the User Guides and Installations Guides, because a Controller can own a vdisk.

Here's the Configuration Guide, which has some good tips, before it arrives to think about.

What about using say an HP MSA70 - as shared storage?

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
MSA70 needs to be connected to an enclosure like a P2000.

But there is or was a P2000, which is a DAS, which can be connected directly to servers.

see here

But you need to confirm with HP if it's supported for VMware ESXi 5.0. It seems to have disappeared from the VMware HCL.
