Anybody here using any of these models? P R O M I S E Technology

I am interested in Rack mounted model -> P R O M I S E Technology

Any feedback appreciated!!

I don't use Promise but I do use a lot of storage systems at work - just ordered 20 of these: http://www-03.ibm.com/systems/storage/disk/ds3000/ds3300/  .   What is your application? How much storage and what bandwidth do you need?  Is it direct attached or?

Note these systems aren't cheap - an IBM DS3300 like the one above fully loaded with 15K SAS and all fully resilient is about $35K USD.  They also consume 1KW power (and cooling to accommodate that load) each and sound like a 747 on takeoff. They're really only suited for use in a data center.  Those points would apply to the Promise as well - all of the above is driven by the disk spindles.

While I have no personal experience with PROMISE RAID systems, Apple replaced its XRAIDs with PROMISE products (http://www.apple.com/server/storage/ ). Try to visit Apple's discussions forums:

don't know what you deployment is, but if you are a single/small photographer, and depending what system you are on, then do be aware that many larger PC workstations can have multi drive Raid storage systems built inside them.
No I'm not talking about 2 drives in Raid1, but 6, 8, or 12 drives in your workstation working through a top level dedicated hardware Raid card, running Raid 5 or 6 (better).
keeping it 'live and local' is a mantra for our needs as photographers.

I have had various systems, but currently have a 12 port Areca Raid 6 card with 10 2Tb drive on it in my computer as I write this: 20Tb total with 16Tb available after Raid 6 takes its two drives for parity. (My case can take 14 drives). Total cost was the card and drives, all from Newegg.com. that's it. all of course available through Ethernet to my assistant/ other users.

with 1.5Tb drives down as low as $80, its pretty easy to get 8 or 10Tb fast + secure RAID storage for under $1000 in a Vista 64 workstation.
