Serial Attached SCSI (SAS) enterprise-class drives designed for high volume, 24x7 usage. Serial-ATA (SATA) are usually reserved for archival of data as they are both relatively inexpensive and are available in very large capacities. The MSA2000 family of arrays can accommodate both SAS and SATA drives within the same enclosure making it ideal to have both business-critical, high activity files on SAS drives while using snapshot or clone capability to keep back-up data on the less expensive drives.

For investment protection, the MSA2300sa G2 controller will support single port SAS & SATA drives in a single-domain MSA70. This support allows current owners of MSA70s to migrate their single port drives (in their MSA70 only) to be attached to an MSA2000sa G2. They can only cascade to another single I/O MSA70. This is not a data-in-place transition.

Optional Disk enclosures

HP StorageWorks 2000sa G2 Modular Smart Array

SAS drive performance can be approximately 30% greater than SATA performance on sequential host IO. SAS performance excels in sequential lower latency response time and random IO per second transaction performance due to higher rpm disk speeds yielding lower seek times.

NOTE:

MSA2 3.5" Large Form Factor (LFF) drives are for use only in

the MSA2000 family.

Just as the user has a choice of chassis for the array head (LFF and SFF drive bays), so also do they have a choice of expansion disk enclosures accommodating either drive size. (NOTE: these are not supported as part of a NEBS-certified with the MSA Carrier Grade Chassis.)

MSA2000 3.5-inch drive enclosure

inch) drive bays and accepts for MSA2 dual-ported SAS and SATA drives. One model (AJ749A) has a single I/O module that matches with a single controller array head, giving a single path to the drives. The second model (AJ750A) comes standard with two I/O modules installed, required when paired with a dual controller array head, giving two paths to the drives for higher availability.

Scalability

This 3.5-inch drive enclosure can be attached to either the LFF or SFF MSA2000sa G2 array head. Each model ships standard with two .6m SAS to SAS cables for cascading to other MSA2000 drive enclosures For connection to either form-factor MSA2300sa array head, miniSAS to SAS cable(s) must be purchased. The single I/O model can be upgraded to a dual model with the purchase of an additional MSA2000 Drive Enclosure I/O module (AJ751A). No cable is included with this upgrade. Up to four MSA2000 3.5-inch enclosures can be attached to an MSA2300i controller in the array head.

MSA70 2.5-inch drive enclosure

B21) is designed to support twenty five ProLiant 2.5-inch Universal form factor (SFF) SAS or SATA hard drives. It ships standard with a single I/O module installed.

This 2.5-inch drive enclosure can be attached behind either LFF or SFF MSA2000sa G2 Array head. The MSA70 enclosure ships with a single .5m miniSAS to miniSAS cable. To support a dual controller MSA2000sa G2 array head, the user needs to purchase and install an MSA70 Dual Domain I/O Module (AG779A). This option ships standard with an additional .5m miniSAS to miniSAS cable. Up to three MSA70s may be attached to the array head, given total support for 99 SFF drives.

The MSA2300sa G2 controller is designed to allow an installation to begin with smaller capacity and be able to grow gradually as needed. The flexibility of SAS or SATA drive technology, form factors, sizes, speeds, and costs per GB allows a system to easily fit in almost any budget.

. This 2U storage enclosure (418800-

Large Form Factor configurations can scale up to 5.4 TB SAS or 12 TB SATA, expandable to 27 TB SAS or 60 TB SATA with the addition of a maximum of four MSA2000 3.5-inch Drive Enclosures. Small Form Factor configurations can scale from 7.2 TB SAS or

6.0 TB SATA. With the addition of three MSA70 JBODs, the MSA2000sa G2 can support 29.7 TB SAS or 24.7 TB SATA.

HP StorageWorks 2000sa G2 Modular Smart Array

Users may configure a 24-drive MSA2000sa G2 SFF array head with up to three 12-drive LFF MSA2000 3.5-inch disk enclosures. This is an excellent method for a configuration that support fast SFF enterprise-class SAS drives in the array head, combined with economical LFF drives staged for archival purposes, all in the same array.

Qualification of larger capacity drives is ongoing.

The MSA2000 family of arrays supports 511 LUNs and LUN sizes up to 16TB. The arrays support LUN expansion and deletion of any LUN.

In addition to the usual RAID levels, the MSA2000 family features several important additional levels. RAID 6 is the highest level of RAID protection. It allocates two sets of parity data across drives and allows simultaneous write operations. It can withstand two simultaneous drive failures without downtime or data loss. RAID 10 is mirroring and striping without parity. It is the most popular of the multiple RAID levels, allowing large arrays with high performance in most cases and superior fault tolerance. RAID 50 combines the block striping and parity of RAID 5 with the straight block striping of RAID 0, yielding higher performance than RAID 5 through the addition of RAID 0, particularly during writes.

HP StorageWorks MSA Storage Management Utility (SMU), Management access, out-of-band: WEB GUI, CLI. Interface Types: Mini DB9 RS232, 10/100 Ethernet Protocols Supported SNMP, SSL, SSH, SMTP, HTTP, Telnet.

The MSA2000sa G2 supports hot plug expansion and replacement of redundant controllers, fans, power supplies, and I/O modules for simple, fast installation and maintenance.

Optional controller based functionality. Offers higher levels of data protection, enabling an almost instant recovery from data failure or corruption. Offers alternative development testing of 'offline' production data and the ability to backup snapped/cloned data.

Performance numbers are a guideline as established by tests using RAW I/O in an Operating System Agnostic test lab environment. A total of 96 72GB 15K SAS drives were used in a dual controller configuration of eight 12 Disk vdisks, eight 806 GB volumes, and two volumes per host. Four hosts directly attached to the MSA2000sa G2 were used in this test configuration (results cannot be expected with a single host). Results were achieved in Sequential Writes with 256K blocks; all random test were based on 8K block sizes. Number and type of applications, drive type, operating system used, and the number of hosts will affect overall performance.
