HP StorageWorks P2000 G3 Modular Smart Array Systems
Drives available | The P2000 G3 controllers support both the P2000 |
| HP ProLiant |
| Serial Attached SCSI (SAS) |
| usage. |
| SAS Midline and SATA Midline are usually reserved for archival of data as they are both |
| relatively inexpensive and are available in very large capacities. |

| enclosure making it ideal to have both |
| Snapshot, clone, or Remote Snap capability to keep |
| drives. |
| For investment protection, the controllers will support single and dual port SAS & SATA drives in a |
| legacy single - or dual - domain MSA70. This support allows current owners of MSA70s to migrate |
| their single port drives (in their MSA70 only, not into the array head) to be attached to a P2000 G3 |
| FC or SAS. They can only cascade to another single I/O MSA70. This is not a |
| transition, and overall performance could be impacted. |
| SAS drive performance can be approximately 30% greater than SATA performance on sequential |
| host I/O. SAS performance excels in sequential lower latency response time and random I/O per |
| second transaction performance due to higher rpm disk speeds yielding lower seek times. SAS |
| drive random performance is generally twice that of SATA drives. |
| NOTE: P2000 and MSA2 |
| or MSA2000 models. The |
| P2000 G3 or the MSA2300 G2 controllers and are common with and are the same part numbers as |
| the ProLiant |
Optional Disk | Just as the user has a choice of chassis for the array head (LFF and SFF drive bays, AC or DC |
enclosures | powered), so also do they have a choice of expansion disk enclosures accommodating either drive |
| size. |
| (NOTE: these are not supported as part of a |
| There is a certified JBOD listed in the |
| P2000 |
| P2000 |
| LFF Drive Enclosure (AP843A) has two I/O modules and supports both single and dual controller |
| arrays. If a single I/O disk enclosure model is desired, the appropriate chassis should be purchased |
| along with a single I/O module (AP844A). |

| Up to seven P2000 |
| Combo, or SAS controller in the array head. |

| The D2700 enclosure ships with a two .5m miniSAS to miniSAS cable. |
| Up to five D2700 may be attached to the P2000 G3 array head, given total support for 149 |
| SFF drives. |
Scalability | The P2000 G3 FC, Combo FC/iSCSI, SAS, 1 Gb or 10GbE iSCSI controllers are 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. |
Large Form Factor configurations can scale up to 7.2 TB SAS or 24 TB SATA, expandable to
57.6TB SAS or 192 TB SATA with the addition of a maximum of seven P2000
Small Form Factor configurations can scale from 7.2 TB SAS or 12 TB SATA. With the addition of five D2700 JBODs, the P2000 G3 FC can support 44.7 TB SAS or 74.5 TB SATA. Users may configure a
Qualification of larger capacity drives is ongoing.
Vdisks | Vdisks can span across multiple enclosures, where drives used in the Vdisk can be contained in |
| different enclosures. The maximum number of drives that can be used in RAID 1 Vdisk is 2; RAID |
| 0, 3, 5, 6, and 10 is 16; and for RAID 50 Vdisk is 32. |
