A little bit offtopic, but if you need something out-of-the-box with professional hardware support you should have a look at Stratus-Avance: http://www.thomas-krenn.com/en/products/complete_solution/stratus-avance-cluster.html It's intel-hardware but actually www.stratus.com/avance runs on IBM as well. And no, I have no experience, no profit and no uncle who is working for one of the companys mentioned above. ;) Regards, Tobias. ___ drbd-user mailing list drbd-user@lists.linbit.com http://lists.linbit.com/mailman/listinfo/drbd-user

Re: [DRBD-user] Could you please recommend hardware?
Hi, Kankamuso! Following up Digimer's reply, at HP the Proliant DL180g6 is also a good model I think : It's available in 25 hot-plug 2,5 HDD slots (or 4, 8 or 12 3.5 slots, but I personnaly prefer the 25 slot version). It's a 2 way Intel server, able to host up to 192GB RAM. One of its best features is its chipset : the same as the one of the DL380, aimed at IOs, which makes it a good candidate for what you intend to achieve. It features 4 PCI-e I/O slots in standard : one 16x, two 8x and one 4x. Enough for instance to host a SmartArray P812 RAID card with 1Gb BBWC, one dual ported 10GbE card for replication (There are 2 internal GbE ports in standard), and whatever you need for something else : FC HBA, additional GbE ports or another P812. It's one of the cheapest HP servers, it will certainly cost below $10k for a comfortable configuration... Well, depends on how many disks you actually need those days... Hope this helps.
