Cache Flush

•

Enabled

: If the controller loses power, it will automatically write cache data to the

CompactFlash card. Cache flush is normally enabled, but is temporarily disabled during

controller shut down.

•

Disabled

: Cache flush is disabled.

Volume cache parameters:

Serial Number

If a volume is specified, its serial number.

Name

If a volume is specified, its name.

Cache Write Policy

If a volume is specified, its cache write policy:

•

write-back

: Write-back caching does not wait for data to be completely written to disk before

signaling the host that the write is complete. This is the preferred setting for a fault-tolerant

environment because it improves the performance of write operations and throughput. This is the

default.

•

write-through

: Write-through caching significantly impacts performance by waiting for data

to be completely written to disk before signaling the host that the write is complete. Use this

setting only when operating in an environment with low or no fault tolerance.

Cache Optimization

If a volume is specified, its cache optimization mode:

•

standard

: Optimizes cache for both sequential and random reads. Appropriate for

applications that read and write small files in random order, such as transaction-based and

database update applications. This is the default.

•

no-mirror

: When this mode is enabled, each controller stops mirroring its cache metadata to

the partner controller. This improves write I/O response time but at the risk of losing data during

a failover. ULP behavior is not affected, with the exception that during failover any write data in

cache will be lost.

Read Ahead Size

If a volume is specified, its read-ahead cache setting:

•

Disabled

: Read-ahead is disabled.

•

Adaptive

: Adaptive read-ahead is enabled, which allows the controller to dynamically

calculate the optimum read-ahead size for the current workload.

•

Stripe

: Read-ahead is set to one stripe. The controllers treat non-RAID and RAID-1 vdisks

internally as if they have a stripe size of 512 KB, even though they are not striped.

•

512 KB

1 MB

2 MB

4 MB

8 MB

16 MB

, or

32 MB

: Size selected by a user.
