IBM System x3850 X6 37
External disk storage expansion
The server supports attachment to external storage expansion enclosures, such as the EXP2500 series,
by using the ServeRAID M5120 SAS/SATA Controller. The server can also be attached to supported
external storage systems, such as the IBM System Storage® DS3500 series, by using a supported HBA
(see the earlier "Storage HBA" section). The following table shows the RAID controllers and options for
external disk storage expansion.
