PERC 5/i RAID Card: Tips and Benchmarks - Page 583

post #5821 of 7172
Wow! It's been like 3 & 1/2 years now and this tread is still going strong. thumb.gif From this Thread, I discovered how to setup my first PERC 5i Controller in the PC I had at the time (long since gone) and had migrated over to PERC 6i . Now I'm looking at upgrading my whole Disk subsystem again to PERC H700 (7i) and move from SAS to SSD. tongue.gif With that, I wanted to see if anyone has any advice and/or suggestions before I receive the equipment I ordered and before I start implementing it. If anyone would be so kind as to review my Posts over here and provide their valuable input I'd greatly appreciate it.

Over all, I'm positive that any answers there would help out numerous people trying to implement the latest PERC H700 in their PCs. So, hopefully it will benefit everyone in the long run. biggrin.gif I thought about posting my Q's in the Thread, but it seemed more appropriate over in the Title of that Thread...


Thanks in advance!

I was wondering if anyone has had any luck with WD20EARS drives in a PERC raid 5 setup? I didn realize WD screwed us on TLER on these new drives when I bought it.

Check out this Forum... Not sure if it will answer any questions you may have, but it helped me to understand thing more clearly';

From what I've heard, you may want to stay away from any Drives that are "Green" Drive in an ARRAY. I currently have the WD "Western Digital Caviar Black WD1001FALS 1TB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive" ( I own 12 of them over all actually, 8 of which are in RAID 5 Arrays off PERC 6i Controllers in different Systems) and I have had absolutely NO issues with them what so ever. However, I'm only using them for Home Office/Small Office use, so they usually never get pounded. Just wanted lots of storage in one location that will perform and will provide some redundancy. I'm happy with what I've got, but I'm starting to need more space as he years progress... Here's my potential answer to my space issues;

I know they're a little more, but they are 3 TB instead of 2 TB and taking that in consideration they are not THAT much more, really, $/GB... Read the reviews on this Drive, as one poster makes a very good point about how much or how little the drives will probably be accessed in a SOHO env.

Hope at least some of of this helps.

Please confirm in this thread but I don't think the PERC 5/6 supports HDDs bigger than 2tb.

edit:***I meant physical hard drives bigger than 2tb, sorry for the misunderstanding***

Miss-read this the first time, so had to edit my post... I'm unsure of that as well, but it definitely supports VDs over 2 TB. Please see my config here;

161

That's one of the reasons I'm moving to the H700, cause from what I've read it sounds like it will support Drives over 2 TB...

Can anyone confirm that?

If I find the answer to this then it will definitely change my migration path to upgrade my Storage Subsystem.

I can confirm that the Perc 5 will support a 2 TB drive, but I cant say for any drives larger than that. Just wished WD hadn't done away with TLER on these drives!!! Not sure what I will do with these 3 WD20EARS now. frown.gif

Also, I looked at the Notes on the latest Dell FW Update for the PERC 6i, which contains history from all previous FW fixes, and it unfortunately does not say anything about physical HDDs larger than 2 TB. Here's the link.

http://ftp.us.dell.com/sas-raid/R313334.txt

I WAS able to confirm that the new H700 definitely does support Physical HDDs larger than 2 TB thought...

http://ftp.us.dell.com/sas-raid/DELL_PERC-H700-ADAPTER_A08_R313326.txt

Also, found this Forum on Dell's site which make it sound like you need to upgrate from PERC 6x to H700+ to support Phy HDDs larger than 2 TB...

http://en.community.dell.com/techcenter/extras/w/wiki/2837.aspx

What I have NOT confirmed is if Flashing with the latest LSI FW will fix the 2 TB limit issue for PERC 6 Controllers. I'm running the latest LSI FW on my PERC 6i's and will post back once I purchase some Physical HDDs > 2 TB. The FW I'm running is;

11.0.1-0042 _SAS_FW_Image_APP-1.40.282-1279_Update1.txt (from .zip)


Cheers...

If it were up to me, (especially if you already own the PERC 5 and the three WD20EARS Drives) I'd say throw them into an Array and test it out. But that's just me... Unless you're going to hit that Array with those HDDs hard, I doubt TLER will be an issue... And if it ends up faulting HDDs out of the Array then tear it back apart and just run them seperate off the PERC or the onboard Controller.

Nothing saying you can't play with your toys! I don't think you're going to seriously strip the life off them by just testing them for a week or two, but I HAVE BEEN WRONG BEFORE... rolleyes.gif

P.S. There's always eBay if you can't use the HDDs in the manner in which you want/need, but I always hate dealing with posting items for sale...

I appears that you are correct, the PERC 5 and 6 models will not support Physical Drives over 2TB. mad.gif For HDDs > 2TB we will need a PERC H700

http://en.community.dell.com/support-forums/servers/f/906/t/19324790.aspx?PageIndex=4

With that, I have a PERC H700 on it's way to my door step. Can anyone please confirm for me that I will need to mask pins 5 & 6 on the top side of the PERC H700 (same as the PERC 5 shown in page 1 that began this Forum) to get around the potential SMBus issue? Please confirm.

Thanks,
