there is on an “online” K2 SAN. However, the files on a Nearline system can be readily available
to an online K2 system via FTP transfer.
The basic Nearline SAN has one Ethernet switch.
The SAN also has one 10 Gig NH K2 Media Server. The NH server for a Nearline system has two
ports for Fibre Channel connections. NH servers do not have media (iSCSI) ports.
A NH server on a Nearline system is configured with roles of FTP server and Media file system
server.
In the Nearline system no K2 Media Servers take the role of iSCSI bridge or media database server.
No K2 clients or any other generic client are part of the Nearline system.
7.2K SAS drives provide the media file storage on a Nearline system. While these drives do not
provide the high bandwidth of the drives required by an online K2 SAN, they offer larger capacity
and lower cost. This makes these drives ideal for the Nearline SAN.
The primary RAID chassis has one controller. The primary RAID chassis is connected via Fibre
Channel to the NH server. The controller in the RAID chassis is also connected to the GigE control
network, which is required for SNMP (NetCentral) monitoring.
There must be one primary RAID chassis and may be up to eleven optional Expansion chassis.
Primary chassis and Expansion chassis contain twelve drives. All disks in both primary and optional
Expansion chassis are bound as RAID 6.
The K2Config control point PC is connected to the GigE control network. The K2Config application
runs on this PC for configuring the SAN. The SiteConfig application also runs on this PC.
