14080 40G appliance:
Two 240 GB removable solid-state drives (SSDs). The two leftmost solid-state drives store the NetScaler software. The
next two solid-state drives store user data. The remaining four solid-state drives are reserved for future use.These
appliances are redundant array of independent disks (RAID) devices. In a RAID configuration, the same data is stored on
multiple drives to improve performance, increase storage capacity, lower the risk of data loss, and provide fault tolerance.
The two SSDs store the same data. If one fails and you replace it, the new SSD mirrors the other one.
