  • Page 15: About The K2 Level 2 Raid Storage

    Chapter About the K2 Level 2 RAID storage This chapter introduces the K2 RAID Storage. Topics include: • “K2 Level 2 RAID features” on page 15 • “K2 Level 2 RAID components” on page 16 • “Configurations” on page 22 K2 Level 2 RAID features The K2 RAID Storage is a high performance, high availability mass storage system.

  • Page 16: K2 Level 2 Raid Features

    Chapter 1 About the K2 Level 2 RAID storage The K2 Level 2 utilizes dual FC-AL technology, allowing two loop configurations within a single chassis. Loop integrity is maintained during failures without user intervention. Each loop and associated circuits along with all other active components are on redundant, separate hot swappable modules.

  • Page 17: Chassis

    Chassis An optional second RAID controller module in the K2 Level 2 RAID, allows for continued access to the K2 Level 2 RAID if the primary RAID controller fails. Adding a second RAID controller to the same chassis is not intended to increase performance, but rather to add redundancy.

  • Page 18: Midplane

    Chapter 1 About the K2 Level 2 RAID storage The following diagram shows how disk modules are identified based on the chassis address and physical location. The chassis with an address set to 0 contains drives from 0 to 14; the expansion chassis with an address set to 1 contains drives from 16 to 30.

  • Page 19: K2 Level 2 Raid Circuit Board Modules

    K2 Level 2 RAID Circuit board modules The disk drives are 3.5-inch FC-AL drives that conform to the Fibre Channel Arbitrated Loop (FC-AL) standards and support dual-port FC-AL interconnects through the two RAID controllers and their cabling. NOTE: Once the K2 Level 2 External RAID is installed and configured, the disk modules become slot dependent.

  • Page 21: Power Supplies

    Power supplies The expansion adapter in the K2 Level 2 has two Fibre Channel ports: FC-IN and FC-OUT. HSSDC (copper) Fibre Channel cabling connects the FC-IN port to a K2 Level 2 RAID. This extends the Fibre Channel loop of the corresponding K2 Level 2 RAID chassis.
