HP StorageWorks 2405 Disk System - Manual (Page 24)

24 Product Description
Single Host Basic Configuration
The maximum number of disk systems supported on a Fibre Channel Arbitrated
Loop (FC-AL) is seven. The maximum storage capacity with this configuration
is approximately 7.5 Terabytes (105 disk modules at the 73 Gbyte capacity
point). This configuration does not provide any redundancy to the data path,
however there is some hardware redundancy provided by the enclosures
themselves (power supplies). With the utilization of Mirror/UX software, one or
more mirrors can be created on the hardware path to provide a basic level of data
protection.
The performance of this configuration depends on the number of disk systems on
the loop. Using the maximum supported number of disk systems reduces the
performance of the loop. To get the maximum performance (200 MB/s or
maximum number of I/Os), the number of disk systems should be limited to four.
