Chapter 4 Managing Stand-alone Storage
Compact Flash — The Compact Flash boot media serves as the system drive of the
K2 Solo Media Server. The Windows operating system, applications, and other
standard computer software components reside on the system drive.
RAID drives — A K2 Solo Media Server contains 2 disk modules. Media data is
written or “striped” across media drives in a continuous fashion, which makes them a
“stripe group”. This media stripe group appears as the V: drive to the Windows
operating system. Disks are configured as RAID 0, so you can not remove and replace
a disk module while the K2 Solo Media Server is operational. If a disk fails, you lose
all media.
Disk controller board — The disk controller board provides the RAID functionality
for the internal disks.
RAID 0 — Disks are configured as RAID 0, so you can not remove and replace a disk
module while the K2 Solo Media Server is operational. If a disk fails, you lose all
media.
About the direct-connect storage system
A K2 Summit Production Client that is directly connected to an external K2 RAID
storage device for media storage is a self-contained, stand-alone unit.
The storage system on an internal storage K2 Summit Production Client includes the
following:
Compact Flash — The Compact Flash boot media serves as the system drive of the
K2 Summit Production Client. The Windows operating system, applications, and
other standard computer software components reside on the system drive.
Fibre Channel card — The direct-connect K2 Summit Production Client has a direct
Fibre Channel connection to external K2 RAID. The K2 Summit Production Client
must have the optional Fibre Channel card installed to support this connection.
There are no internal RAID drives or a disk controller board in a direct-connect
storage K2 Summit Production Client.
RAID 5 — Drives configured as RAID 5 provide redundancy. There are six disks in
one RAID 5 LUN. A disk in a LUN can fail and disk access can continue. When a
disk fails, error messages in the AppCenter StatusPane or in NetCentral inform you
of the problem. You can then replace the failed disk. The data is rebuilt on the
replacement disk and redundancy is restored.
