LSI SAS 2308 RAID Controller – HBA Information and Listing

4
Posted May 30, 2012 by Patrick Kennedy in Servers

As we have seen with the latest server processors such as Sandy Bridge-EP and Ivy Bridge, PCI Express (PCIe) 3.0 is becoming widely available. To address this LSI has released a PCIe 3.0 controller, the LSI SAS 2308 to provide additional bandwidth over its PCIe 2.0 SAS 2008 controllers. The LSI SAS 2308 is a 6.0gbs SAS 2 or SATA III based controller that features eight ports and native PCIe 3.0 connectivity. In the forums we have maintained a LSI Controller Mapping between LSI controllers and their OEM counterparts. This post will be updated with both information on the LSI SAS 2308 based RAID controllers as well as the different OEM models commonly found in the marketplace. Oftentimes LSI SAS 2308 controllers are less expensive when found as OEM parts from Intel, Dell, HP, IBM, Supermicro and others, so it makes sense in many cases to purchase the OEM versions of the LSI SAS 2308 based cards.

    As a side note, I tested the LSI 9205-8e and found its performance for data warehousing (sequential reads) to be identical to the 9200-8e, which was surprising. I hope (and expect) that a PCIe3 card with the same controller would show better performance.
    Patrick, if you need a pile of SSD drives to test one of these cards in a socket 2011 machine, let me know.

    Will see what I can get to play with. One interesting note is that I have heard PCIe 2.0 cards off of an Xeon E5 PCIe 3.0 bus are showing better latency. Have not had time to try this myself.

    Officially the LSI9205 is a PCIe Gen2 card, even though the SAS2308 is a PCIe Gen3 Chipset.
    The only real difference really is the 800Mhz SAS208 vs the 533Mhz SAS2008, other than that they are pretty well the same.
    You may notice a difference with 8x SATA3 SSD’s as the SAS2308 can probably handle a more throughput, but otherwise the SSD’s will be the bottleneck.

    HP H220/221/222 are all LSI 2308 based HBA.
