Solid-state drive configuration rules for the 8248-L4T, 8408-E8D, or
9109-RMD
Before you install and configure solid-state drives (SSDs), you must review the supported machine type
model, the supported expansion unit or enclosure, adapter, and configuration details.
SSD drive rules for a system, enclosure, or expansion unit
Solid-state drives, also known as flash drives, follow similar rules as a regular hard disk drive (HDD).
For example, SSDs physically resemble, install in the same manner, and in most of the same slots as
HDDs. However, some restrictions and configuration rules are specific to the SSD. The following tables
helps you determine the operating system, adapter, machine type model, and disk drive configuration
rules that apply to your system or expansion unit.
After you review the configuration rules, you can install the drive as you would any other disk drive. For
more information about installing disk drives or solid-state drives, see the topic collection for your
system or expansion unit.
Restriction: Solid-state drives must be part of a RAID array or system mirroring in the system or logical
partition that is controlled by IBM i.
See the Table 1 for the system or partition or the enclosure or expansion unit where you want to install
drives.
Attention:
Before you install SSD in your system, ensure that both the SSD and the adapters have all
the prerequisite updates. To check for the prerequisites, go to the IBM Prerequisite website
(www-912.ibm.com/e_dir/eServerPrereq.nsf).
