Lack of love for storage questions on the forum

post #1 of 3
Thread Starter 
I've posted a few questions on RAID as I learn about it but I don't get much love here. My questions are about medium home RAID arrays for file storage. Is there another forum a few people here go to for networking and storage advice? This doesn't seem like the place to ask such questions as this is an overclocking forum so most questions here are about RAID and controllers for RAID 0. All I'm asking for is advice about cheaper set-ups for home +4 HDD arrays. Benchmarks don't matter and it's not to support a business so cheaper drives that may fail aren't much of an issue if I can save a few hundred dollars. Someone suggested the Dell PERC 6/i 6i PCI-e SAS SCSI Raid Controller Card from e-bay. But it looks a little old. Is it stable? Which cables are better? SAS to SATA or mini-SAS to SATA? This Supermicro AOC-SASLP-MV8 Marvell 6480 8 Channel SAS/SATA RAID PCI-E Card on NCIX is cheaper then the dell. Whats the difference between the two? My current HDDs are full and instead of buying a 1 or 2 TB drive I'd like to start investing in a large, expandable RAID 5 setup. 2TB drives slowing growing to a total of 8.

Advice?!

Instead of the Perc 6/i, go with the Perc 5/i, fantastic for what it costs. (~$100 on eBay, with BBU if you're lucky!)

Perc 5/i is cheaper, but supports upgradeable RAM. However, the Perc 6/i supports RAID 6 and 60.

Though if you're going to eventually go to 8 drives, but will start off with say, 4. I would go with the Perc 5/i and just do two separate RAID 5's. Seeing as RAID 6 is just like RAID 5, but x2. (2 Redundant drives for RAID 6, where as RAID 5 is 1, but with two separate RAID 5's it would still be 2 backup drives.)

I have yet to purchase my card and drives, but that is what I intend to do. Best bang for your buck, since direct from Dell they can cost 5x as much.

Also, a whole thread talking about the Perc 5/i and 6/i here: http://www.overclock.net/raid-controllers-software/359025-perc-5-i-raid-card-tips.html

(Not sure if you saw that or not!)

Also, the Supermicro isn't really a RAID card at all, it's a controller card that just allows for 8 drives to be hooked up, so you wouldn't get any redundancy or data security if a drive fails. It supports JBOD which is literally, "Just a Bunch Of Drives (Discs)". So that is definitely a reason why it's cheaper then the Dell 6/i (but not the 5/i, if you wait for the good deals on eBay!)

Hope this shamble of information has helped!

Sites like OCN, HardForum and eXremeSystems, as much as they are all aimed at PC enthusiasts, have their own flavour or focus. OCN is very much focused on gamers and benchers, hence the focus on CPU and graphics card overclocking.

To answer your questions however: both the PERC 5/i and PERC 6/i are solid choices, and can be found for silly bargains on eBay. The PERC thread on this site is an excellent information resource. The AOC-SASLP-MV8 is a troublesome card, so I advise you to stay away from it.
