[ILUG] Dell PERCs and Linux

[Gary Mc Closkey]

	We bought a Dell P'Edge at Christmas. Came with a PERC2/SC and RAID5 . It is a rebadged 16MB AMI megaraid, at happily works on RH6.1/2.2.12 .

	The PERC2/DC used to be something else, and not linux compatible at that time. Don't know about their current offering though. I believe there is a Dell head on the list though.

	In following several RAID mail-lists for a while, the Megaraid was consistently accused of uninspiring if reliable performance. There was also a general consensus that the Mylex were fast and sexy.

	Must say that for our (undemanding, office file sharing, email, web server) stuff, the Megaraid has been fine with RAID5.

	If someone wants to suggest a benchmark, I'll be happy to run it and report back.

+-----Original Message-----

+Dell are telling me that the PowerEdge RAID controller (PERC2/SC and
+PERC2/DC) are now working with Linux.  The Linux source code (2.2.16)
+indicates that these are badged AMI MegaRAID cards - does anyone know
+for sure?
+
+I believe that the MegaRAID cards have performance problems with RAID5;
+anyone confirm/deny?  I'd only really plan on using RAID1 anyway (or
+possibly 1+0 if I can fit enough disks in).  The alternative is,
+obviously, the Mylex eXtremeRAID 2000, which looks like being the
+fastest LVD RAID card around...
+
+Final thoughtlets?
