Family Information
HP StorageWorks P2000 G3 Modular Smart Array Systems
LUNs | The HP StorageWorks 2000 family of arrays supports 512 LUNs (total volumes in a dual controller | ||||||
| system) and LUN sizes up to 16 TB. The array supports expansion and deletion of any LUN. | ||||||
RAID 0, 1, 3, 5, 6, 10, | In addition to the usual RAID levels, the P2000 G3 features several important additional levels. | ||||||
50 | 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. |

Performance | Performance numbers are a guideline as established by tests using RAW I/O in an Operating | ||||||
| System Agnostic test lab environment. 144 GB 15K SAS drives were used in a dual controller | ||||||
| configuration of 12 vdisks consisting of twelve disks per vdisk, 1.6 TB volumes, and 3 volumes per | ||||||
| host. 4 hosts directly attached to the P2000 G3 array 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 tests were based on 8K block sizes. |
|
|
| |||
| NOTE: Number and type of applications, drive type and number of drives, operating system used, | ||||||
| and the number of hosts will affect overall performance. This table is provided strictly as a | ||||||
| comparison. Note: These numbers reflect a full array configuration with the maximum number of | ||||||
| |||||||
| designed to give a reference point for comparisons. They will be reposted shortly when finalized. | ||||||
