Currently, IBM RAID controllers can be categorized into three major types based on the hard drives they control:
SCSI RAID controllers for SCSI hard drives:
ServeRaid, ServeRaid II, ServeRaid 3L, ServeRaid 3H, ServeRaid 4L, ServeRaid 4Lx, ServeRaid 4M,
ServeRaid 4Mx, ServeRaid 4H, ServeRaid 5i, ServeRaid 6M, ServeRaid 6i/6i+, ServeRaid 7e, ServeRaid 7k;
SATA RAID controllers for SATA hard drives:
ServeRaid 7e, ServeRaid 7t;
SAS RAID controllers for SAS hard drives and hot-swap SATA hard drives:
ServeRaid 8e, ServeRaid 8i, ServeRaid 8k, ServeRaid 8k-l, ServerRaid 8s
Next-generation RAID controllers for SAS hard drives and hot-swap SATA II hard drives:
ServerRaid MR-10i, ServerRaid MR-10m, ServerRaid MR-10k;
Classification by integrated vs. optional RAID controllers:
Motherboard-integrated RAID controllers: ServerRaid 7e, ServerRaid 8e
Optional RAID controllers: ServerRaid 7k, ServerRaid 7t, ServerRaid 8i, ServerRaid 8k, ServerRaid 8k-l, ServerRaid 8s, ServerRaid MR-10i, ServerRaid MR-10m, ServerRaid MR-10k
Below is a detailed introduction of several new RAID cards (SCSI RAID cards are early-generation cards; please refer to the following link for more information: http://publib-b.boulder.ibm.com/Redbooks.nsf/RedbookAbstracts/tips0054.html?Open#ServeRAID):
