Question before buying PE1950&MD1000

[Cesar Vergara (MMP)]

Ok. I am aware of that, but i have made some informal tests between 2
desktop pcs. One been my "SAN" with 2 internal 160GB SATA HD (1 SATA as the
boot device and the 2nd simulating the external array). Then installed
SLES10 SP1 on both machines, the SAN was running the iSCSI Target and the
client was running VMWARE Server 1.0.4 (Free) and from inside the
Virtualized Oses (1 w2k3 with MS-Initiator and 1 SLESSP1 with Linux iSCSI
Initiatos), i can conect to the exported discs from the SAN.

The difference with the Dell setup, is that i want :

- the PE1950 to boot from the iSCSI through the Intel PT1000 NICs from the
SAN.
- VMWARE to load the Virt'zd Oses files from the iSCSI SAN.
- Virt'ed Oses to connect to the iSCSI SAN.

I can tell that the SAN will be full with jobs. But i think it would be just
in certain momento ( boot, and Image loads) then i expect to have a SPOF on
my SAN side. I hope i cant change VM servers as fast a reboot from the SAN
images.

The Next phase of this setup is to have GFS or some to share the iscsi
filesystem between 2 or more servers

Thanx

Nothing really wrong with you setup, but you might want to verify your setup
against the MD1000 matrix listed below (specifically Vmware version, I don't
see VMserver listed...  only Vmware ESX). 
Note the "note" listed below pulled from the linked matrix:

NOTE: Dell PowerVault MD1000 is supported to provide external storage to a
single ESX host or maximum of two hosts in a split configuration. Features,
such as VMotion, HA and DRS, that require shared storage among ESX hosts are
not supported with MD1000.

lity_matrix_current.pdf


Also, here is a link to the MD1000 supported. Configuration which it appears
SLES10 is listed, so it should Install pretty clean:

If it were me, I would go with the MD3000i and VmwareESX setup once Vmware
lists the MD3000i on the support matrix.
You can backend 2 x MD1000's to the MD3000i if you need to expand storage in
the future as well.

Importance: High

Hi:

I'm from far Peru and i have this question:

I have 3 PE2950 running database & FileServer (but under w2k3)

Now i want to make an small SAN & Virtualization these way:

Buying:
- 2 PE1950 2xXeonQuad5405-2Ghz-32GB-NoHD-IntelPT1000,DualPortNIC
- 1 PE2950
1xXeonQuad5405-2Ghz-4GB-2x160SATA-RAID1-IntelPt1000,DualPortNIC,
conected to
- 1 MD1000 7x750GB-SATA-RAID5

I want to :
- install SLES10SP1 on PE2950 RAID1 discs,
- PXE-Boot the PE1950's SLES10SP1 from the PE2950. 
- activate the iSCSI Target for the MD1000 discs on the PE2950 and the iSCSI
Initiators from the PE1950,
- use VMWARE VMServer 1.0.4 (2.0 is still crude) on the PE1950,
virtualizaing some SLES (with iSCSI Init) & W2K3 (With MS-iSCSI Init)

It's posible or factible or i just go with an MD3000i or an PE6950 with all
the ram and all the discs and do virtualization on it?
