Cache

To enable faster data access from disk storage, the following types of caching are performed:

• Write-back or write-through caching. The controller writes user data in the cache memory on the

module rather than directly to the drives. Later, when the storage system is either idle or aging — and continuing to receive new I/O data — the controller writes the data to the drive array.

• Read-ahead caching. The controller detects sequential array access, reads ahead into the next

sequence of data, and stores the data in the read-ahead cache. Then, if the next read access is for cached data, the contr oller immediat ely loads the data into the s y stem memory, avoiding the latency of

a disk access.

NOTE: See HP P2000G3MSA System SMU Reference Guide for more information about volume cache

Controller Module

CompactFlash

options.

Transportable CompactFlash

During a power loss or array controller failure, data stored in cache are saved off to non-volatile memory (CompactFlash). These data are then written to disk after the issue is corrected. To protect against writing incomplete data to disk, the image stored on the CompactFlash is verified before committing to disk.

In single-controller configur ati on s, i f the contr o ller has f ailed or does no t start , and the C ac he S tatu s LED is on or blinking, the CompactFlash will need to be transported to a replacement controller to recover data not flushed to disk (See Controller failure in a single-controller configuration on page 51 for more information).

CAUTION: To preserve the existing data stored in the CompactFlash, you must transport the

CompactFla sh f rom the failed controller to the r e placement controller using a procedure outlined in the HP Controller Module Replacement Instructions, shipped with the replacement control ler. Failure to use this

procedure will result in the loss of data stored in the cache module. The CompactFlash must stay with the same enclosure. If the CompactFlash is used/installed in a different enclosure, data loss/data corruption will occur.

IMPORTANT: In dual controller configurations featuring one healthy peer controller, there is no need to

transport a failed controller’s cache to a replacement controller because the cache is duplicated between the controllers.

Super-capacitor pack

To pr otect RAID controller cache in case of pow er failure , P2000 G3 MSA Sy stem contr ollers ar e equipped with super-ca pacitor technology, in conjunction with CompactFlash memory, built int o each controller module to provide unlimited cache memory backup time. The super-capacitor pack provides energy for backing up unwr itten data in the w rite cac he to the CompactF lash in the e vent of a po w er failure . Un wr itten data in CompactFlash memory are automatically committed to disk media when power is restored. While the cache is being maintained by the super-capacitor, the Cache Status LED flashes at a rate of 1/10 second on and 9/10 second off.

See the racking instructions poster. optional dri ve enclo sur es in the rac k , and attach ear caps.

2. Connect contr oller enclosur e and LFF/SFF

drive enclosures.

See Connecting controller and drive enclosures on

page 24.

3. Connect power cords. See the installation poster.

4. Test enclosure connections. See Testing enclosure connections on page 33.

5. Install required host software. See Host system requirements on page 37.

6. Connect data hosts. See Connecting the enclosure to data hosts on

page 37.

7. Connect remote management hosts. See Connecting remote management hosts on

page 39.

8. Obtain IP values and set management

port IP properties on the controller enclosure.

9. Perform initial configuration tasks

• Sign in to the web-based storage

management application (SMU).

• Initially configure and provision the

storage system using SMU.

See Obtaining IP values on page 41.

See Connecting to the controller CLI port; with Linux

and Windows topics.

Topics below correspond to bullets at left:

See “Getting Started” in the HP P2000G3MSA

System SMU Reference Guide.

See “Configuring the Sys tem” and “Provisioning the

System” topics (SMU reference guide or online help).

MSA Device Discovery Tool, introduced in Obtaining IP values, provides the optimal method for setting network port IP addresses.

SMU is introduced in Accessing SMU on page 45. See the SMU reference guide or online help for additional information.

NOTE: For optimal perfor mance, 6Gb P2000 G3 MSA Sys t em contr oller enclosures should be cabled to

6Gb P2000 G3 MSA System drive enclosures when expanding storage capacity.

P2000 G3 MSA System controller to drive enclosure cabling is described within this chapter. Cabling of 3Gb driv e enclosures to newer 6Gb controllers is addressed for custo mers upgrading existing legacy systems.
