Also a HP P4500 (Lefthand) user here, have just added our third node in to give us more disk space. Because that node acts as both controller and diskshelf, our overall I/O throughput capacity increases with each one we add.
Have got our main SQL Servers virtualised on to vSphere, all running off the P4500's at the backend, have never seen any performance worries. If you're strapped for cash, have a look at the HP Renew program, especially if you're in the US where there's an abundance of HP P4000 series kit, can usually pick up a starter pack with 3-5 year 24x7 support contract for a good discount. http://www.hp.com/united-states/renew-worldwide/index.html -----Original Message----- From: Paul Hutchings [mailto:[email protected]] Sent: 31 January 2011 19:49 To: NT System Admin Issues Subject: RE: iSCSI SANs vs FibreChannel SANs I've spent most of this afternoon installing the second site in a three site (2 data, 1 FOM) P4000 setup. There's been a few "WTF?!" moments mostly around the CMC and reporting, but it's kind of neat to have your live data in two locations and be able to lose one and have it fail over damned near seamlessly (vsphere HA isn't great). I suspect Oliver's decision may be made when he sees how much even a pretty basic FC switch costs.

Not cheap, but cheaper than a lot of them, and they've been acquired by HP. Never had an ounce of trouble with them - a RAM stick went bad on one of them, and HP hotfooted a replacement to me with no issues. No downtime, either, because of the two way replication. I shut down the affected unit as soon as I got the RAM, replaced the stick, fired it back up, and nothing so much as hiccuped. Needed to seriously update the software when adding in the third unit, but a support rep held my hand over the phone, and that went smoothly, too. Awesome stuff.
