Hardware
The following section provides a summary of the front and back panel hardware features of Vess A6600, and
Vess A6800 Storage Appliance for Video Surveillance. These enclosures are referred to collectively as Vess
A6000 enclosures, Vess A6000 units or Vess A6000 subsystems throughout this document when the content
applies to all models in the Promise Vess A6000 Series.
Front Panel Hardware
The front panel of Vess A6000 enclosures provide access to drives carriers. Vess A6000 units are shipped with
secure covers to protect the drive carriers from being unintentionally removed.
For all Vess A6000 enclosures, defective drives can be replaced without interruption of data availability to the
host computer. If so congured, a hot spare drive will automatically replace a failed drive, securing the fault-
tolerant integrity of the logical drive. The self-contained hardware-based RAID logical drive in the Vess A6000
provides maximum performance in a compact external enclosure.
