Preface
The programmable LUN mapping feature allows flexible specification of the LUN
to system drive mappings. Specific LUN ID (or multiple LUN IDs) can be
assigned to any system drive on each channel or use a default setting. Ownership
of a system drive can be assigned to any combination of controller/channel,
known as System Drive Affinity.
The Ultra S2S RAID Controller now supports an optional battery backup module
for maintaining memory content in case of an AC power failure. Its principle
purpose is to provide ride-through during a power glitch, however, the battery
backup module is capable of sustaining memory content for hours at a time,
depending on the type and size of installed controller memory.
Another new feature is Drive Sizing. Previously when a drive failed it was
required to be replaced with a drive of equivalent size. If a larger capacity drive
was used, its capacity was defined as that of the smallest drive in the array. With
Drive Sizing, the user can specify how much of the drive's total capacity should
be used. This permits the user to make various size drives and make them appear
to all be the same size from the perspective of the Ultra S2S RAID Controller.
