Upgrades

At some point you may have a need to upgrade your storage system to increase
the storage capacities and/or the RAID capabilities. The NexStor 4900F Series
Storage System provides you with this ability to meet your expanding data
storage requirements.
The RAID controllers support a feature know as "drive roaming," where the
controllers can keep track of which drive belong to which logical arrays. In the
event the drives' enclosure is changed or the drives are moved to another
enclosure attached to the same set of controllers, the arrays will not be lost or
damaged.
The upgrade process is relatively easy, refer to the "Operating Mode Configuration
and Cabling" section for the new topology for your configuration. Install the new
components, set the SES Controller Card switches, the Host I/O card(s) switches
and the Disk I/O cards jumpers for the new configuration settings, then cable the
storage system enclosures as indicated.
