January 22, 201115 yr Hi! I need a new controller for my Supermicro C2SEE. Can both be used with this mobo? Where is the difference? Bye.
January 22, 201115 yr Besides the obvious difference of PCI-X (SAT2) vs. PCI-E 4x (SASLP) bus interface, the SASLP uses SFF-8087 internal connectors on the card which means 2 breakout cables are required for use with SATA drives. The SAT2 has 8 SATA ports on the card (can get messy depending on how many drives you have). The SASLP also uses Marvell's 88SE6480 controller while the SAT2 uses Marvell's 88SX6081 controller. In terms of cost, the SAT2 will be overall less expensive because it comes with 8 SATA cables and the SASLP needs 2 forward SFF-8087 to 4 SATA breakout cables. I would recommend the SASLP due to the PCI-E 4x bus but that's just me. Probably wouldn't see much difference in real world use.
January 22, 201115 yr You absolutely want the SASLP since the SAT2-MV8 will place all drives on the PCI bus. Parity check is extremely slow (about 15-20 percent of the speed with all slots full). Everyday performance is not affected. I used to run a SAT2-MV8 in a PCI slot, now I run two in PCI-X slots and they are speedy.
January 22, 201115 yr Author Hi! Thanks for the input. I think I will go with the SASLP. They cost round about 20€ more than the SAT2. And they will fit into my mobo? Bye.
January 22, 201115 yr And they will fit into my mobo? Yes, these are the slots your mobo has, you need PCI e x4 for the SASLP 6. 1 (x16) PCI-Express 2.0, 1 (x4) PCI-Express (using x16 slot), 1 (x1) PCI-Express, 4x 32-bit PCI slots Josh
June 4, 201115 yr You absolutely want the SASLP since the SAT2-MV8 will place all drives on the PCI bus. Parity check is extremely slow (about 15-20 percent of the speed with all slots full). Everyday performance is not affected. I used to run a SAT2-MV8 in a PCI slot, now I run two in PCI-X slots and they are speedy. Just to double check, only the drives connected to the SAT2-MV8 would be on the PCI bus, which does not affect, say, the drives connected directly to the motherboard SATA ports, correct? I was looking into the SASLP until I read the bad reviews on Newegg.
June 4, 201115 yr Do we have any information on whether the SASLP supports 3TB drives? If not, Supermicro say that the USAS2-L8i does. The USAS2 costs a little bit more than the SASLP, but if 3TB support may become important to you, it would be worth considering. The USAS2 is a x8 2.0 device (actually a UIO card so needs adjustment of the backplate), so would be best installed in the x16 slot.
June 4, 201115 yr Do we have any information on whether the SASLP supports 3TB drives? Yes we do. Look at http://lime-technology.com/forum/index.php?topic=11183.msg109527#msg109527 In short, unless you use ancient hardware, almost all controllers support 3Tb drives (as data drive, not boot drive). It is just waiting for unRAID support to use them...
