Questions about PCIe SAS RAID Cards



  • Hi all. We are currently building a server and have a couple questions. Could someone assist me with these?

    We are currently using a link textSuperMicro Chassis . This case has a SAS / SATA Hard Drive Backplane with SES2. Our current motherboard included the I-pass->4 sata port breakout cable. We are wanting to connect the new PCIe SAS RAID Card to the backplane, but did not know if these breakout cables are usually included with the card or if we will have to order one depending on the connectors on the card.

    Also is there any benefit from purchasing a PCIe 3.0 card versus PCIe 2.0? Will the bandwidth from the 3.0 ever be fully utilized?



  • Extra bandwidth is used when the cache is used. It can be quite a bit bursting over the line.



  • Thanks Scott. Also there are 2 4pin connectors on the backplane for the fault LEDs. Is this something that I will need to purchase separately (the old cable had this included in the ipass cable)?



  • If expect SuperMicro to supply that.



  • Thanks Scott. We decided to go with a good LSI PCIe 3.0 card.

    Good choice. Did you get one with CacheCade?
