ServeRAID M5210 12Gb/s SAS/SATA controller

The IBM ServeRAID M5210 is a 12Gb/s SAS/SATA controller designed for servers that need to connect internal drives through a PCI Express 3.0 x8 slot. It suits administrators who manage RAID arrays on SAS or SATA storage.

Plug-in card with two SFF-8643 connectors

The card uses a plug-in form factor and provides two SFF-8643 ports for direct attachment of drive backplanes or cables. Each port supports 12Gb/s SAS and Serial ATA links, so mixed drive types can share the same controller.

Upgrades from earlier 6Gb/s SAS RAID cards

Moving to this 12Gb/s controller doubles the per-lane bandwidth available to each attached drive compared with 6Gb/s SAS RAID cards. The jump is worth it when newer SSDs or HDDs would otherwise be limited by the older controller interface.

Questions about this item

What host interface does the ServeRAID M5210 use and what does the PCI Express 3.0 x8 link cap in practice?

The ServeRAID M5210 connects via a PCI Express 3.0 x8 host interface, which caps the controller's host bandwidth at the x8 lane limit while the SAS side runs at 12Gb/s per port.

What physical slot and bracket does the ServeRAID M5210 plug-in card need to fit in the server?

The ServeRAID M5210 is a plug-in card that requires a PCI Express x8 or wider slot and ships with a full-height bracket for standard server chassis.

How is the ServeRAID M5210 installed and which step involving the SFF-8643 connectors is often missed?

Install the card into a PCI Express x8 slot, then attach Mini-SAS HD cables to the two SFF-8643 ports; the step often missed is securing the cable latches so the 12Gb/s links stay reliable.
