Lenny on HP DL 380 G5 with P400 (SAS HBA) / CCISS vs. HPSA
Hi, I'm currently using HP DL 380G5 for various tasks: - Mail server - Database server - File server I sometimes find the performance of the disks to just be average. A new driver (HPSA) is making its way into the kernel for more than a year now (intended to replace the CCISS driver). Do you guys have any input on replacing CCISS by HSPA ? Did you get any performance gain ? Thanks for the input. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?
