HP sas expander and a HP P411 raid card, reduced to 450

resmon.exe

With the price of the power supplies, I was thinking the same thing. I was throwing this together for a friend's business, for storing backups, but with the power to run a few VM's. Now the scope has changed to "I think we'll use it to replace our server" and "we must have redundant power"...

Hello everyone, I have a norco 4220. I currently have a standard 850w power supply installed. My norco's mission is about to significantly change. Can anyone point me to redundant power supplies (650+), that come in the "standard" W x H power supply form factor? The depth doesn't matter...

There are also the tiny ssd 310 m-sata ssd's from intel.

I bought these new from provantage last year. Everything works properly, and I will upgrade it to the latest firmware before shipping.

Your solution... http://hardforum.com/showthread.php?t=1459008 Even with screws scavenged from other cards, they were hard to thread in. So don't break your card... I wound up using and destroying one screw as a tap (while off the card), before I was able to get any screws that I had on hand...

Where your editing program stores its undo/changes information is probably more important. If you have enough ram to store the original file in memory, it probably doesn't matter if the original file is on in the file cache or on a ram disk. It's just the original file. Once it's in memory, it's...

Absolutely true! I have a w2k8 r2 system with 64gb of ram. It regularly retains 10gb - 20gb files in memory. In 32-bit Windows you could set a cap on the amount of ram used for file cache. But in 64-bit, you can't. As far as I can tell, any attempts to cap the file cache size are ignored by...

For Sale - Combo of a HP sas expander and a HP P411 raid card, with 512MB battery backed write cache. $450 takes both.

Yes, and same brand/model. LSI 9280-8e--> cable--> LSI sasx36 expander--> cables--> backplane (BPN-SAS-846A)--> disks. I have tried to make it fail by copying a bunch of large files from disk to disk, and running iops benchmarks. But it doesn't fail when I try to stress it. It just seems...

Has anyone seen this error, after running for a month or so? Controller ID: 0 SAS topology error: SMP function failed. Then ALL virtual disks drop off of the raid controller. I've had this happen twice. 28 days apart, using two different sas expanders. After a reboot, the raid disks appear...

Dell, SuperMicro, etc., do not write their own firmware for products based on LSI chips. LSI writes the firmware. Then the OEMs can turn features on/off via software/firmware switches, and release their own "custom" firmware.

Just like the pic in this pmc-sierra sas doc, section 2.1, figure 3, page 10. It's an older doc, but marvell and pmc sierra both tout support for 3gb disk multiplexing in their chips. But I wonder if it would only work only with 3gb sas disks (not sata). I guess someone could call ATTO and...
