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 controller immediately loads the data into the system memory, avoiding the latency of a disk access.
20 Components
NOTE: See HP P2000 G3 MSA System SMU Reference Guide for more information about volume cache options.
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 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 55 for more information).
Controller Module
CompactFlash
CAUTION: To preserve the existing data stored in the CompactFlash, you must transport the CompactFlash from the failed controller to the replacement controller using a procedure outlined in the HP Controller Module 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 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.
To protect RAID controller cache in case of power failure, P2000 G3 MSA System controllers 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 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 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.

3If the systems are cabled for replication and licensed to use the Remote Snap feature, you can use the Replication Setup Wizard to prepare to replicate an existing volume to another vdisk. See the SMU reference guide for additional information.
NOTE: For optimal performance, 6Gb P2000 G3 MSA System controller 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 drive enclosures to newer 6Gb controllers is addressed for customers upgrading existing legacy systems.
NOTE: For information on NEBS Level 3-compliant carrier-grade enclosures, see http://www.hp.com/products1/servers/carrier_grade/products/cgblades/enclosure.
HP P2000 G3 FC MSA System User Guide 23
P2000 G3 MSA System controller enclosures — available in either 24-drive (2.5”) or 12-drive (3.5”) chassis — support up to eight enclosures (including the controller enclosure) for storage/expansion, or a maximum of 149 disk drives. You can also configure drive enclosures of mixed type, as shown in Table 3 on page 26.
The firmware supports both straight-through and reverse SAS cabling. Reverse cabling allows any drive enclosure to fail — or be removed — while maintaining access to other enclosures. Fault tolerance and performance requirements determine whether to optimize the configuration for high availability or high performance when cabling. P2000 G3 MSA System controller enclosures support both 3Gbps and 6Gbps internal disk drive speeds, together with 3Gbps and 6Gbps expander link speeds. Controller and expansion modules are identified by <enclosure-ID><controller-ID>. When connecting multiple drive enclosures, use reverse cabling to ensure the highest level of fault tolerance.
For example, Figure 6 on page 29 shows controller module 1A is connected to expansion module 2A, with a chain of connections cascading down (blue). Controller module 1B is connected to the lower expansion module (5B) of the last drive enclosure, with connections moving in the opposite (reverse) direction (green).
NOTE: P2000 G3 MSA System controller enclosures support hot-plug replacement of redundant controller modules, fans, power supplies, and I/O modules. Hot-add of drive enclosures is also supported.
Connecting controller and D2700 6Gb drive enclosure
A D2700 6Gb drive enclosure, supporting 6Gb internal disk drive and expander link speeds, can be attached to a P2000 G3 FC MSA System LFF or P2000 G3 FC MSA System SFF controller enclosure using supported mini-SAS to mini-SAS cables of 0.5m to 2m length (see Figure 3 on page 28).
Connecting controller and P2000 6Gb 3.5" 12-drive enclosure
A P2000 6Gb 3.5" 12-drive enclosure, supporting 6Gb internal disk drive and expander link speeds, can be attached to a P2000 G3 FC MSA System LFF or P2000 G3 FC MSA System SFF controller enclosure using supported mini-SAS to mini-SAS cables of 0.5m to 2m length (see Figure 2 on page 28).
Connecting controller and MSA70 3Gb drive enclosure
P2000 G3 MSA System controllers support MSA70 3Gb drive enclosures running firmware version 2.18 or later.
For information about the MSA70 3Gb drive enclosure, 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.
If you connect a 3Gb drive enclosure to a 6Gb controller enclosure, data throughput occurs at the drive enclosure’s 3Gb data rate (see Figure 5 on page 29).
Diagrams within this document use IOM (I/O Module: also referred to as expansion module).
Connecting controller and MSA2000 3Gb 3.5" 12-drive enclosure
Connecting an MSA2000 3.5” 12-drive enclosure to a P2000 G3 FC MSA System LFF or P2000 G3 FC MSA System SFF requires supported mini-SAS to SAS cables. If you connect a 3Gb drive enclosure to a 6Gb controller enclosure, data throughput occurs at the drive enclosure’s 3Gbps data rate (see Figure 4 on page 28).
IMPORTANT: Adding a fourth drive enclosure 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. Select your product. Quickspecs links are located on the right.
24 Installing the enclosures
Connecting controller and mixed drive enclosures
P2000 G3 MSA System controller modules support cabling of 3Gb and 6Gb SAS link-rate LFF and SFF expansion modules — in mixed fashion — as shown in Figure 10 on page 32, and as further described in Additional cabling considerations (below); the HP P2000 G3 MSA System Cable Configuration Guide; and HP white papers (listed on the following page).
Additional cable requirements for drive enclosures
IMPORTANT:
•When installing SAS cables, use only supported SAS 4x cables with connectors supporting your application (6Gb, 3Gb, or both).
•Mini-SAS to mini-SAS 0.5m cables are provided with each of the following drive enclosures (one per expansion module): P2000 6Gb 3.5" 12-drive enclosure and D2700 6Gb drive enclosure.
•If additional or longer cables are required, they must be ordered separately (see relevant MSA2000 G2 Quickspecs or P2000 G3 Quickspecs for your products).
•The maximum cable length allowed in any configuration is 2m.
•When expanding storage capacity, a maximum of eight enclosures — including the controller enclosure — or one hundred forty nine (149) disk drives are allowed in the array.
P2000 G3 MSA System cable requirements
Figure 1 (below) and Table 4 on page 27 jointly describe cabling requirements and connection combinations for P2000 G3 MSA System components. Components are labeled with back-end SAS data rates and other relevant attributes. Simplified IOM face plates are shown.

1One 0.5m cable is required per controller module to I/O (expansion) module connection.
2One 0.5m, 1.0m, or 2.0m cable is required per controller module to expansion module connection.
NOTE: Additional cabling notes:
•Cables required, if not included, must be separately purchased.
•When adding more than two drive enclosures, you may need to purchase additional 1m or 2m cables:
•Spanning 3, 4, or 5 drive enclosures requires 1m cables.
•Spanning 6 or 7 drive enclosures requires 2m cables.
•See Table 4 on page 27 and related footnotes for cabling multiple drive enclosures.
IMPORTANT: Controller modules within the enclosure must be of the same type. Do not install an HP P2000 G3 FC MSA System and HP P2000 G3 SAS MSA System controller module in the same chassis.
IMPORTANT: Connecting 3Gb and 6Gb drive enclosures limits performance and should be done only when upgrading legacy product configurations.
For additional information concerning cabling of P2000 G3 MSA System controllers and MSA2000 G1 or G2 drive enclosures, visit your HP MSA products page http://www.hp.com/go/p2000. From the HP MSA products page, browse for the following reference documents:
•HP P2000 G3 MSA Best practices
•HP MSA2000 Family Best practices
•Upgrading the HP MSA2000 G2 to the P2000 G3 MSA
•Upgrading the HP MSA2000 G1 to the P2000 G3 MSA
Additional cabling considerations
P2000 G3 MSA System controller enclosures (both LFF and SFF models) support each of the drive enclosures listed above. However, when cabling supported drive enclosures of mixed type, consider the following factors regarding components equipped with SAS2.0 and SAS1.1 expanders (labeled in Figure 1 on page 25):
•P2000 G3 MSA System controller enclosures support 6Gb and 3Gb drive enclosures.
•To avoid performance limitations in a mixed-type drive enclosure environment, cable 3Gb drive enclosures after 6Gb drive enclosures as shown in Figure 10 on page 32. Do not mix 6Gb and 3Gb disk drives in the same enclosure.
•Performance will be limited if a 3Gb drive enclosure is cabled before a 6Gb drive enclosure — and cannot be avoided — if reverse cabled. A 6Gb drive enclosure will perform at a 3Gbps data transfer rate if cabled after a 3Gb drive enclosure.
