QuickSpecs

HP MSA P2000 G3 Modular Smart Array Systems

Family Information

8Gb Fibre Channel	Two host ports per FC controller shipped with SFPs. The P2000 G3 FC controller can run in either point-to-
controller	point or FCAL (loop). The default is FCAL which is used in Direct Connect, particularly with two controllers.
	The PtP (fabric) mode is used with almost all switches.
Combo controller with	This ingenious dual-protocol "combo" controller supports a full FC SAN through the 8Gb FC ports, while
FC and iSCSI ports	designating the two 1 GbE iSCSI ports to enable remote replication over iSCSI protocol and perform as an
	iSCSI target. This allows economical sharing of the storage resource (the P2000 G3 array) with one
	department needing the performance afforded by the 8 Gb FC ports while simultaneously supporting
	another department with lesser performance needs and a budget only allowing a 1GbE iSCSI network.
6Gb SAS controller	Four 4x host ports per 6Gb SAS controller.
10GbE iSCSI controller	Two 10GbE ports per G3 10GbE iSCSI controller. Ports are ready for the choice of SFP (none included)
	Supports the ProCurve and ISS versions of the following 10GbE parts for use in the controllers:
	HP 10Gb Cables
	HP SFP+ 10GbE Copper Cable
	HP ProCurve 10-GbE SFP+-SFP+ Direct Attach Cable
	HP SFP+ Transceivers
	HP BladeSystem 10Gb SR SFP+ and HP BladeSystem 10Gb LRM SFP+
	HP ProCurve 10-GbE SFP+ SR Transceiver and HP ProCurve 10-GbE SFP+ LRM Transceiver
	No SFP+ LR Transceiver support
1 Gb iSCSI controller	Four 1 Gb Ethernet iSCSI ports per G3 iSCSI controller
Modular Chassis	2U rack height. 12 Large Form Factor or 24 Small Form Factor drive bays, accommodating SAS and SATA.
	Comes with space for one or two controllers, or P2000 3.5-inch disk Enclosure I/O modules (LFF chassis
	only)
Drives available	The P2000 G3 controllers support both the P2000 3.5-inch Large Form Factor (LFF) drives, and the HP
	Storage 2.5-inch Small Form Factor (SFF) drives.
	Serial Attached SCSI (SAS) enterprise-class drives are designed for high demand, 24x7 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.
	The HP entry-level 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, clone,
	or Remote Snap capability to keep back-up or archival data on the less expensive 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 data-in-place 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 3.5-inch Large Form Factor (LFF) drives are for use only in the P2000 G3 or
