If you're looking to put a load of disk in for say ZFS have you tried flashing to a none RAID firmware so it uses mps instead of mfi? Regards Steve ----- Original Message ----- From: "Achim Patzner" To: Sent: Monday, September 10, 2012 1:38 PM Subject: mfi driver performance Hi! We’re testing a new Intel S2600GL-based server with their recommended RAID adapter ("Intel(R) Integrated RAID Module RMS25CB080”) which is identified as mfi0: port 0x2000-0x20ff mem 0xd0c60000-0xd0c63fff,0xd0c00000-0xd0c3ffff irq 34 at device 0.0 on pci5 mfi0: Using MSI mfi0: Megaraid SAS driver Ver 4.23 mfi0: MaxCmd = 3f0 MaxSgl = 46 state = b75003f0 or mfi0@pci0:5:0:0: class=0x010400 card=0x35138086 chip=0x005b1000 rev=0x03 hdr=0x00 vendor = 'LSI Logic / Symbios Logic' device = 'MegaRAID SAS 2208 [Thunderbolt]' class = mass storage subclass = RAID and seems to be doing quite well. As long as it isn’t used… When the system is getting a bit more IO load it is getting close to unusable as soon as there are a few writes (independent of configuration, it is even sucking as a glorified S-ATA controller). Equipping it with an older (unsupported) controller like an SRCSASRB (mfi0@pci0:10:0:0: class=0x010400 card=0x100a8086 chip=0x00601000 rev=0x04 hdr=0x00 vendor = 'LSI Logic / Symbios Logic' device = 'MegaRAID SAS 1078' class = mass storage subclass = RAID) solves the problem but won’t make Intel’s support happy. Has anybody similar experiences with the mfi driver? Any good ideas besides running an unsupported configuration?
