Description of K2 Storage Devices


This chapter contains descriptions of the devices that make up the K2 Storage System, as follows:

Control point PC description

A control point PC runs applications from which you operate, configure, and monitor the K2 Storage System. You can have one or more PC that provide control point functionality. However, you must have only one designated control point PC on which you install and run the K2 System Configuration application.

The primary applications that can run on a control point PC are as follows:

Refer to Overview of K2 Storage Tools for descriptions of these applications.

You can purchase a control point PC from Grass Valley. In this case the PC has all the above software pre-installed at the factory. When you receive the PC it is ready to install on the K2 Storage System control network and begin using with minimal configuration.

You can also build your own control point PC by installing and configuring software on an existing PC. Refer to Managing K2 software for instructions.

Control point PC system requirements

If you are building your own control point PC, the machine you chose must meet the following requirements. These requirements assume that the PC is dedicated to its function as the control point for the K2 Storage System and that no other applications run on the PC that could interfere with system performance.

Control point PC system requirements are as follows:

  • Microsoft Windows XP Professional, Service Pack 2
  • 400 MB hard disk space
  • Minimum 512 MB RAM, 1 GB recommended.
  • Microsoft .NET Framework 1.1
  • Graphics acceleration with at least 128 MB memory
  • Java JRE 1.3.1_12 and 1.4.2_05
    This is required for the HP Ethernet Switch configuration interface.
  • Pentium 4 or higher class processor, 2 GHz or greater

K2 Ethernet switch description

The K2 Ethernet switch provides the primary network fabric of the K2 Storage System. The switch supports Gigabit Ethernet connections, which provides the bandwidth required for the iSCSI media traffic.

The recommended K2 Ethernet switch is a HP ProCurve Switch 3400cl-24G. This switch has been tested and qualified for the K2 Storage System. The switch is a store-and-forward device offering low latency for high-speed networking. In addition, the switch offers full network management capabilities.

You can also use a Cisco Catalyst 3750 Gigabit Ethernet switch, as supplied by Grass Valley, if required by your site.

Refer to the manuals that you receive with the switch for more information.

K2 Level 1 RAID storage description

For the level 1 K2 Storage System, the RAID storage device takes the role of both media server and RAID storage. The SCSI connection between the media server and the RAID disks is therefore internal only, which means no Fibre Channel connections or separate RAID storage devices are required. This allows iSCSI clients to connect via the Gigabit Ethernet fabric to the L1 RAID storage device. The L1 RAID storage device uses the same chassis as the Grass Valley K2 Media Client product and repurposes components found in that product and in the K2 Media Server to provide the combined functionality required for level 1 K2 storage.

The L1 RAID storage device includes a Windows operating system PC which runs the media server applications. It has one iSCSI interface adapter, which provides the Gigabit Ethernet iSCSI media port for the media network.

The L1 RAID storage device houses 12 internal disk drives and a SCSI RAID adapter. The drives are configured as six RAID 1 LUNs of 2 drives each. One LUN is the system drive and the other five LUNs provide the shared media storage.

For servicing information on the L1 RAID storage system, refer to the K2 Level 1 RAID Storage Instruction Manual.

K2 Level 2 RAID storage description

The K2 Level 2 RAID Storage is used in Level 2 and Level 2R K2 Storage Systems. The RAID storage device is a high performance, high availability mass storage system. The L2 RAID chassis 2Gb/s host interface supports industry standard Fibre Channel technology.

The L2 RAID chassis utilizes dual FC-AL technology, allowing two loop configurations within a single chassis. Port-BypassCircuits have been added to maintain loop integrity during failures without user intervention. Each loop and associated Port Bypass Circuits along with all other active components are on redundant, separate hot swappable modules. With two RAID Controllers, the two loops within a single standard chassis are configured as a single loop with a backup loop in standby mode.

The L2 RAID chassis contains from fifteen half-height 3.5" Fibre Channel Arbitrated Loop (FC-AL) disk drives. The chassis also supports one or two hardware RAID Controllers in one 3U high rack-mountable chassis.

The L2 RAID Expansion Chassis provides additional storage capacity. The Expansion Chassis has one or two Expansion Adapters installed, but has no LAN card. Only one L2 RAID Expansion Chassis can be connected to a single L2 RAID chassis comprising a single disk-array storage system with a total of 30 drives.

NOTE: Grass Valley does not support mixing disk drives of differing capacities in a file system stripe group.

For servicing information on the L2 RAID storage system, refer to the K2 Level 2 RAID Storage Instruction Manual.

K2 Level 3 RAID storage description

The K2 Level 3 RAID Storage is used in Level 3 and Level 3R K2 Storage Systems. The RAID storage device is a high performance, high availability mass storage system. The L3 RAID chassis 2Gb/s host interface supports industry standard Fibre Channel technology.

Four FC host ports are available, so that the L3 RAID chassis can be connected directly to up to four media servers without Fibre Channel switches. The L3 RAID chassis utilizes dual FC-AL technology, allowing four loop configurations within a single chassis. Port-BypassCircuits have been added to maintain loop integrity during failures without user intervention. Each loop and associated Port Bypass Circuits along with all other active components are on redundant, separate hot swappable modules. With two RAID Controllers, the two loops within a single standard chassis are configured as a single loop with a backup loop in standby mode.

High-performance RAID processors that enable inter-controller communication at 2GB/s are installed to implement the shared memory system. This feature not only enhances the performance, but also helps dynamic load balancing of the host interfaces.

The Switch based disk enclosures permits high-speed access to the disk drives being used.

The L3 RAID chassis contains from fifteen half-height 3.5" Fibre Channel Arbitrated Loop (FC-AL) disk drives. The chassis also supports one or two hardware RAID Controllers in one 3U high rack-mountable chassis.

The L3 RAID Expansion Chassis provides additional storage capacity. The Expansion Chassis has one or two Expansion Adapters installed. Up to seven L3 RAID Expansion Chassis can be connected to a single L3 RAID chassis comprising a single disk-array storage system with up to 120 drives.

NOTE: Grass Valley does not support mixing disk drives of differing capacities in a file system stripe group.

For servicing information on the L3 RAID storage system, refer to the K2 Level 3 RAID Storage Instruction Manual.
