RE: Opinion on rebuilding Raid 5
In my opinion Raid 5 on Everything is just wrong. You have to use the appropriate Raid Level for you specific needs. I had a consultant several years ago that said Raid 5 was the absolute best for their application. As a matter of fact they said it was best in all occasions. I then setup two servers one with Raid 5 and another with Raid 10 for a demonstration. I have to say for their application Raid 10, killed Raid 5. They were not allowed to consult for us again, as a matter of fact they continued to say that our test with the same hardware and processors was invalid and Raid 5 was the best in all circumstances. I do like to report that their company is no longer in business, for some reason they lost all of their customers. -Original Message- From: Holstrom, Don [mailto:dholst...@nbm.org] Sent: Monday, April 11, 2011 9:07 AM To: NT System Admin Issues Subject: RE: Opinion on rebuilding Raid 5 With the huge sizes hard drives can reach, is RAID5 still better than, say, mirrored drives?

Raid 10 vs Raid 0+1 RE: Opinion on rebuilding Raid 5
I have a question about Raid 10 vs Raid 0+1... I understand the fundamental differences between the two: One is a raid 1 of two raid 0s, and the other is a raid 0 of two raid 1s... Obviously, the raid 10 allows any two disks to die, which I see as an advantage. Is there some kind of speed improvement with the Raid 0+1 which is beneficial? As far as I can tell, I would think not... as the raid 0+1 would require twice the mirroring, and the raid 10 would only require twice the striping... which I imagine is easier for the controller to do. (Or do I have Raid10 and Raid 0+1 backward?) Also, if you had 8 disks in a raid 10, do you get (Total Space/2), or (4 * (Total Space of 2 drives/2))? Another way to ask: would you have a (Raid0(Raid1(Disk1)(Disk2))(Raid1(Disk3)(Disk4))(Raid1(Disk5)(Disk6))(Raid1(Disk7)(Disk8))) or would you have a (Raid0(Raid1(Disk1)(Disk2)(Disk3)(Disk4))(Raid1(Disk5)(Disk6)(Disk7)(Disk8)))? I'm sure the answer to this question is It depends on your raid card. But I'm curious on what people use and what experiences they have. Personally, I've been using Raid 5 or Raid 6 for years, as speed has not been an issue for us... until very recently. --Matt Ross Ephrata School District - Original Message - From: Crawford, Scott [mailto:crawfo...@evangel.edu] To: NT System Admin Issues [mailto:ntsysadmin@lyris.sunbelt-software.com] Sent: Mon, 11 Apr 2011 10:27:54 -0700 Subject: RE: Opinion on rebuilding Raid 5 Theoretically, you could lose half your drives without failure with RAID1...but they need to be the right half.

Re: Opinion on rebuilding Raid 5
It also depends on what you use it for. For reading the performance difference is not as dramatic as for writing, especially as you add more disks. For writing the difference will improve with more disks, but will still be less than half of raid1.

RE: Opinion on rebuilding Raid 5
If you're using Exchange 2010 then you're still not going to be pushing a lot of IOPS. It could be more of an issue if you had a SQL or intensive ERP app etc. It isn't black and white IMO. Buy a SAN like an Equallogic and all your disks are in one big RAID set. Buy a dumber SAN like an MD3000i and you can have as few or as many RAID sets as your physical disks support, buy a P4000 and your nodes give you redundancy as does your RAID level, so you see what I mean, it isn't a one size fits all thing really. -Original Message- From: John Aldrich [mailto:jaldr...@blueridgecarpet.com] Sent: 08 April 2011 17:42 To: NT System Admin Issues Subject: RE: Opinion on rebuilding Raid 5 Well, I don't think we'll have a whole lot of IOPS, unless / until I bring email in-house, in which case I might just have it on it's own dedicated server with plenty of disk space on-board and back that up to the SAN. :-) -Original Message- From: Paul Hutchings [mailto:paul.hutchi...@mira.co.uk] Sent: Friday, April 08, 2011 12:24 PM To: NT System Admin Issues Subject: RE: Opinion on rebuilding Raid 5 You need to weigh up price vs. performance needs vs. risk tolerance.

If you're just going to use your SAN for general storage, why not just get a cheaper drive array, or even JBOD? The cost of SAN storage is MUCH higher than general storage warrants.

Re: Opinion on rebuilding Raid 5
I thought we'd disabused you of the notion that you need a [high end] SAN? Granted the high end ones are nice and they have their uses, but your just looking to store files on it. Are you going to virtualize all your servers, rely on Vmotion or some other tool to ensure high availability, or do you need to provide data access to a large number of disparate servers? Consider looking at some of the lower end offerings from Synology and Qnap (heard good things), and avoid Drobo (heard not so good things) and stay away from Buffalo (don't touch that, it's pure evil). This project has been on your dockett for over a year now, hasn't it? Awaiting funding? The Synology and Qnap offerings are pretty affordable, and get you into iSCSI access realm. Also, whatever happened to your project about setting up your own storage server? With Windows Server 2008 R2 having access to the iSCSI target software MS recently released, that becomes an option now, too.

RE: Opinion on rebuilding Raid 5
Tbh from the various posts you've made on the subject, when you get around to it, you shouldn't have too hard of a time. With respect, you've spent a lot of time talking about it, but download ESXi and FreeNAS/P4000 VSA and just experiment with a test box and iometer/jetstress and the likes. I wouldn't let the RAID level be your deciding factor, but of course it plays a part. -Original Message- From: John Aldrich [mailto:jaldr...@blueridgecarpet.com] Sent: 08 April 2011 17:55 To: NT System Admin Issues Subject: RE: Opinion on rebuilding Raid 5 Yeah I was keeping that in mind...

RE: Opinion on rebuilding Raid 5
Yes, I plan on virtualizing servers for H/A purposes. Yeah... long-term project with the problem of no funding. The original recommendation when I first started here was to use a NAS and a couple small pizza box servers for domain controllers. Wish I'd gone that route now. The problem I see with a JBOD is that I want to share the storage out over two different servers for H/A reasons. Currently we use DFS to mirror the files on two servers. I don't like that. I want something better, but still be able to share the files out over both servers, so that if one goes down, I can quickly switch people to the other one. To me, that means a small, low-end SAN. No, I don't need a high-end SAN. You are correct that a Tier 2 or lower SAN vendor would probably be more than sufficient for what I need. I originally had grand plans for mirrored SANs, with one off-site, but have come to realize that is probably more expensive and complicated than we can afford, not to mention we don't have the bandwidth for it. :-) At this point, my plans are for a storage appliance of some sort backed up to tape (speed of restore is not critical. Simply being able to restore it *is* critical.) Also, I want to convert my big, massive Dell servers into VMWare hosts and run a couple virtual domain controllers on each one, with the virtual servers themselves being loaded off the storage appliance. I think that should be sufficient, if not slightly overkill.

Opinion on rebuilding Raid 5
So I have a Dell 2850 with 6 drives in raid 5 and one completely failed and another is predicted to according to the OpenManage software. I replaced the failed one and it's rebuilding but I was wondering if anyone has an opinion on whether or not I can replace the suspect drive before the other one completes it's rebuild as this is a remote office and I really don't want to drive back out here just to swap a drive out.

If you don't have a hot spare then NO! If you do have a hot spare, then it should have kicked in when the previous drive failed, and you would currently not be seeing any rebuilds with the drive you already replaced...

Re: Opinion on rebuilding Raid 5
What does Dell Server Support say? I can't remember the details, but a firmware and OpenManage upgrade later, my failed drive was back up and running. I can't remember the details because it was 2-3 years ago. This was a 2550 which whose service contract had run out like 3 years previously. Despite the bad press Dell sometimes gets in this forum, the techs are only concerned with whether or not they can get your server back up and running, not whether or not you have a valid support contract.

Re: Opinion on rebuilding Raid 5
When you do replace the system add a couple of drives for spares but gloss over that detail unless really questioned on it. Your new machine would then have 2 hot spares. I usually would also bundle in the full 5 year service contract on replacement servers for this reason as well when working for the state. Don't lie but don't highlight the upgrades. This usually will not get the bosses upset and make yours and their lives a little easier down the road when you go asking for something.
