ServeRAID M5110 and M5110e SAS/SATA Controllers for IBM System x

Feature upgrade matrix
The ServeRAID M5110 and M5110e provide support for RAID 0, 1, and 10 as standard capabilities.
Additional functional upgrades optionally are available to expand the standard capabilities. Some
upgrades do not depend on other upgrades and can be applied to "out-of-the-box" controllers (we call
them primary upgrades). Certain upgrades cannot be applied to "out-of-the-box" controllers and require
that other upgrades are enabled before applying these upgrades (we call them secondary upgrades).
There are two types of available upgrades: hardware (HW) and Feature on Demand (FoD). Hardware
upgrades contain physical parts (for example, cache module or battery). FoD upgrades are software
licenses. The following table lists the available primary upgrades, their capabilities, and types.
