Cache
To enable faster data access from disk storage, the following two types of caching are performed:
• Posted-write 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 controller immediately loads the data into the system memory, avoiding the latency of
a disk access.
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.
4 Service port (used by service personnel only)
5 SAS Out port (connects to another drive enclosure)
6 Optional I/O module
In single-controller configurations, if the controller has failed or does not start, and the Cache Status 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 56 for more
information.)
HP StorageWorks 2000sa G2 Modular Smart Array User Guide 19
CAUTION: To preserve the existing data stored in the CompactFlash, you must transport the
CompactfFlash from the failed controller to the replacement controller using a procedure outlined in the HP
StorageWorks 2312sa/2324sa G2 controller replacement instructions, shipped with the replacement
controller. 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, 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 protect RAID controller cache in case of power failure, the 2312sa G2 and 2324sa G2 are equipped
with super-capacitor technology, in conjunction with CompactFlash memory, built into each controller
module to provide unlimited cache memory backup time. The super-capacitor pack and CompactFlash
memory in each controller module provide unlimited cache memory backup time. The super-capacitor pack
provides energy for backing up unwritten data in the write cache to the CompactFlash in the event of a
power failure. Unwritten data in CompactFlash memory is 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.

Connecting controller and drive enclosures
Connecting controller and MSA2000 3.5" 12-drive enclosures
You can connect up to four MSA2000 3.5" 12-drive enclosures to a 2312sa G2 and up to three MSA2000
3.5" 12-drive enclosures to a 2324sa G2. The cabling diagrams shown in this section show the
recommended fault-tolerant cabling patterns. Connecting an MSA2000 3.5" 12-drive enclosure to a
2312sa G2 or 2324sa G2 requires mini-SAS to SAS cables.
IMPORTANT: Adding a fourth drive enclosure to a 2312sa G2 may require a separate, longer cable. For
a current list of supported cables, check the MSA2000 G2 QuickSpecs located on the HP MSA products
page at http://www.hp.com/go/msa
QuickSpecs link is located on the right.
When connecting multiple drive enclosures, use reverse cabling to ensure the highest level of fault
tolerance. Controllers and I/O (expansion) modules are identified by
<enclosure-ID><controller-ID>. For example, Figure 3 on page 24 shows controller 1A
connected to I/O module 2A, and the chain of connections continuing down. Controller 1B is connected
to the lower module (B) of the last drive enclosure in the chain, with connections moving in the opposite
direction.
Connecting controller and MSA70 2.5” 25-drive enclosures
The 2324sa G2 can also be attached to an MSA70 running firmware version 2.18 or later. For information
about the MSA70, including detailed steps to upgrade the firmware, see the HP StorageWorks 70 Modular
Smart Array Enclosure User Guide located on the MSA2000 Software Support/Documentation CD
shipped with your product, or at http://hp.com/support/manuals
. Select MSA SAN Arrays, and then select your product. The

Connecting controller and mixed-connect 3.5” and 2.5” drive enclosures
You can connect LFF MSA2000 3.5" 12-drive enclosures and SFF MSA70 2.5” 25-drive enclosures to a
2324sa G2 controller enclosure in mixed-connect fashion, as shown in Figure 6 on page 26, and as
further described in the following documents:
• HP StorageWorks MSA2000 G2 Installation Instructions
• HP StorageWorks 2000 G2 Modular Smart Array Cable Configuration Guide
These documents also address connection of the controller enclosure to either LFF or SFF drive enclosures.
A few sample connection diagrams are provided in Figures 1-5 on the following pages.
Additional cable requirements for drive enclosures
IMPORTANT:
• When installing SAS cables, only use supported SAS 4x cables with 3Gb connectors.
• SAS to SAS 0.6m cables are provided for the MSA2000 3.5" 12-drive enclosure (one per controller).
• Mini-SAS to mini-SAS 0.5m cables are provided with the MSA70 drive enclosure (one per controller).
• The maximum cable length allowed in any configuration is 2m.
• If additional or longer cables are required, they must be ordered separately (see MSA2000 G2 Quick
Specs).
• When expanding storage capacity, a maximum of five enclosures
ninety-nine (99) disk drives are allowed in the array.
