Arrays

3-56 ISR654602-00 H

 Product Revision is the product revision of the LUN as reported by the

SCSI INQUIRY command.

 Target Type for the array can be specified as either Source, Destination,

Src+Dest (both source and destination type), or None.

 Array Bandwidth (for source targets) can be specified as one of the

following: Slow (50BMB/s), Medium (200BMB/s), Fast (1600MB/s), User

Defined, or Max Available.(This field is shown only for source arrays.)

 User-defined Bandwidth (MB/s) becomes available if the selected Array

Bandwidth setting is User Defined. (This field is shown only for source

arrays.)

 Load Balancing is either Enabled or Disabled for this array.

 Maximum Concurrent I/O (for source targets) indicates the maximum

quantity of data migration I/Os that can be issued concurrently to the source

storage array. The default is 128. If the storage array can handle a larger

number of I/Os, select 256. If the storage array cannot handle 128 I/Os,

select 64. This setting is used to control the migration I/O to a source array,

depending on the host I/O activity. (This field is shown only for source

arrays.)

 Enable I/O Pacing to control automatic throttling and pacing of migration

I/O. I/O pacing is used during data migration to limit I/O on a single array

from consuming the iSR6200's bandwidth, and to maximize host and

migration I/O performance. The iSR6200 intelligently manages concurrent

migration I/Os to maximize overall migration throughput. If a queue full or

busy condition is detected, the iSR6200 throttles the migration I/O until it

detects the array’s queue full or busy condition. When the condition is

cleared, it starts issuing more migration I/Os. (This field is shown only for

source arrays.)

 LUN Info Display determines whether the array’s LUNs are identified by

LUN ID, WWULN, or Serial Number.

 Breakup IO is either Enabled or Disabled for this imported array. Enable

this setting to break up into smaller packages the I/O from the remote

system. (This field is shown only for imported arrays.)

 Compression is either Enabled or Disabled for this imported array. Enable

this setting to compress data on the blade before sending it to the peer

(remote) blade during remote migration using native IP. Compression

improves the performance of the I/O. (This field is shown only for imported

arrays.)

 Arra

y License shows whether or not a data migration array license has

been applied to the array.
