4.7 Internal disk storage options
This section provides information about the internal storage options. The RAID
controller cards and the conventional and solid-state disks (SDDs) that are
supported also are listed.
The IBM NeXtScale nx360 M4 server supports one of the following drive options:
򐂰 One 3.5-inch simple-swap SATA drive
򐂰 Up to two 2.5-inch simple-swap SAS or SATA HDDs or SSDs
򐂰 Up to four 1.8-inch simple-swap SSDs
Rules for mixing drive types:
򐂰 Mixing HDDs: Simple-swap SATA HDDs and simple-swap SAS HDDs can be
intermixed in the system, but cannot be intermixed in the same RAID array.
򐂰 Mixing HDDs and SSDs: Both simple-swap SATA HDDs and simple-swap
SAS HDDs can be intermixed with SSDs in the system. SAS or SATA HDDs
cannot be configured with SSDs within the same RAID array.
