Chapter 1 About the K2 Lx0 RAID
The K2 Lx0 RAID Expansion Chassis provides additional storage capacity. It
contains:
• Two Expansion Adapters
• Up to eleven K2 Lx0 RAID Expansion Chassis can be connected to a single K2
Lx0 RAID chassis
• A single disk-array storage system with up to 144 drives
K2 Lx0 RAID components
The K2 Lx0 RAID components are:
• One 2U high rack-mountable chassis
• One or two (K2 Lx0 RAID redundant) RAID controllers or two expansion adapters
(Expansion chassis)
• As many as twelve SAS 73GB or 300GB (15,000 rpm) or SATA 500 GB or 750
GB (7,200 rpm) disk drives per chassis
• Two RAID chassis power supplies
All configurations have SNMP ports, slots for primary and secondary controllers, and
chassis with redundant power. Any unoccupied slot (RAID controller or disk module)
has a filler module to maintain air flow and compliance with electromagnetic
interference (EMI) standards.
The RAID controllers, expansion adapters, disk drives and power supplies are
hot-swappable field replaceable units (FRUs), which means you can add or replace
them while the K2 Lx0 RAID is powered up.
An optional second RAID controller module in the K2 Lx0 RAID allows for
continued access to the K2 Lx0 RAID if the primary RAID controller fails. Refer to
the K2 Storage System Instruction Manual for detailed connection and configuration
instructions.
