At first I had to think what you were saying, but then it dawned on me, you are talking about the height. Yes, you are right, 3.5mm max height is 25mm. and most 2.5" drives are in a range of 7mm-15mm for height. Now I realize that may be a big problem, but I will measure them when I get home. Let's hope they are 12.5 or less. haha

You might notice an increase in general usage, but don't expect a night-and-day transformation (although this does depend heavily on your usage patterns).
Yeah I was afraid of this, but I figured since I gotta take apart the existing raid and figure out if the drives are failing, why not go sas. if the 2.5 10K drives don't work out, i got a pair of 15k 73g 3.5 waiting nearby. I just wish you could turn off some the features of SAS to make it faster. Full Duplex mode for SAS instead of half duplex for SATA would seem like it would be faster but I know that is wishful thinking.

2.5" drives are either 9mm, 12mm or 15mm thick - I have never seen a SAS drive that was not a 15mm thick drive. Sorry...

Not sure what you want to turn off that would make it faster - SAS is already faster all round than SATA. The Duplex mode isn't really an issue though - the heads can only either read OR write at once, so being able to transfer data in 2 directions is really pointless.

Hey, I was wondering if someone could help me out with the issue I'm having with my Dell SAS6/iR (LSI 1068E). The firmware is pretty recent (late 2009), but I cannot configure the RAID array. I have an Intel P965 Chipset, and I had to block off the two pins so my system would post. I used a piece of tape temporarily. I have two 15k SAS Drives that i'd like to configure in RAID0.

So, I am able to get into the LSI BIOS (Ctrl+C), and I can see the adapter and both of my SAS drives, but in the menu for the controller, there isn't a "RAID Options" button/menu. I can see the SAS Topography and the Advanced options menu, but there isn't a RAID menu! Does the SAS6 not support RAID in a non-Dell system? I looked it up, and it says it's supports hardware RAID0 & 1. What should I do?

Thanks!

anyone know how the PERC5i does against the LSI 9240-8i?

Just letting you know that I magaged to get my VD back online, yay!

Importing foregin config didn't work (gave an error).
Deleting the VD and importing foreign config didn't work either

In the end, I craeated a new VD with the same specs as the old one and chose not to initialize the VD. It took a few seconds and then all was good. Note that I did this with all the "old disks" plugged in.

To make sure all was OK, I ran a "Check integrity" which didn't return any errors.

Note that all this was done from the PERC BIOS. I will never try expanding the array from within Windows again.

Thanks for the help BLinux!

Has anyone set up a RAID 50 array on the Perc 5/i? It supports it according to this paper:
http://www.google.com/url?sa=t&sourc...jxp6fi8jJXS8KA

It's a nice quick read. Here is a chart from it:

Ok, I've just about had enough of this minor problem. Anytime my server loses power, the PERC 5/i isn't recognized when it boots back up. It's a pain in the ass to have to go to my server closet, open up the case, disconnect/reconnect the battery, and then button it all back up every time I have a power outage. Is there a way to fix this?

If not, I was thinking of rigging a momentary switch inline on one of the BBU wires. The question is which one? At least that way I can have a battery reset switch on the front/back of the case and not have to open it up every time. Any thoughts?

I hope this hasn't been answered before. I searched as best I could and the only thing I found was another user with the same problem but no resolution.

@zigian

What firmware are you running?
post #4719 of 7194
All right my second OCZ Vertex 2 60GB should arrive Monday, so after that I've left with 2 choices:

1) Expand my current RAID5 array by 3 more 500 GB disks, totaling 8 500GB disks.

2) Convert the array to RAID50 (not even sure how I would do this.....have to research more on it.

I've already backed up essential stuff to other sundry drives, so if all failed I would only lose my movies, which frankly isn't that big of a deal.
