•
Up to 224 LUNs with LUN partitioning enabled (require Navisphere Supervisor or Navisphere
Manager, both running on NT)
•
Up to 32 LUNs without LUN partitioning
•
Dynamic RAID volume expansion (with LUN partitioning feature)
•
2 global hot spares, with rebuild priority adjustment (configurable threshold for the minimum
number of IO reserved for server use during rebuild). The capacity of a hot spare disk must be at
least as great as the capacity of the largest disk module that it might replace.
2.1.4.8. Performance figures
•
8400 IO/s from SP cache, with dual SP
•
120 MB/s with dual SP
These values are measured from SP cache to servers. They represent the processing power of the SP,
and the maximum performance that could be obtained with optimal configuration. In real
configurations, performance is lower, and mainly depends on the number of disks: less disks means
low throughput and low read/write I/O rates.

Interface to host
•
Fibre Channel interfaces of 100 MB/s (1 SP) or 200 MB/s (2 SPs).
•
