Product Highlights

HP StorageWorks Modular Smart Array 30 Single Bus or Dual Bus Enclosures

Upgradeability	Upgrading a StorageWorks 4200/4300 Enclosure to a MSA30 is as easy as swapping out the I/O
	module and the EMU on the back of the unit. The unit must be powered down to replace the I/O
	unit.
	NOTE: U320 performance requires a compatible U320 controller. This is noted in the product
	documentation. A U320 compatible EMU is also required for upgrades to U320 I/O modules.

Mix and Match	All Ultra320, Ultra3, and Ultra2 devices from HP are compatible with one another so customers
	can mix and match components in the same storage enclosure or server. When Ultra2, Ultra3,
	and Ultra320 devices are found on the same Ultra320 SCSI bus, each device will transfer data at
	its individual interface transfer rate up to the transfer rate of the SCSI bus. (Requires an Ultra320
	controller for each drive to reach maximum I/Os as listed here.)
	NOTE: For customers who operate legacy Models 4310R and 4350R enclosures, the use of 1-
	inch Universal Ultra2, Utlra3, or Ultra320 disk drives requires the addition of 0.6-inch drive
	extenders. For configurations using the PCI-X Dual Channel U320 SCSI HBA, (P/N A7173A),
	mixing disks types (U160 and U320) is not supported in the same MSA30 enclosure.

Hot Pluggable	Hot pluggable technology is designed into drives, redundant power supplies and redundant
	cooling fans. Hot pluggable components can be replaced without powering down the storage
	system or stopping I/O operations. This feature significantly enhances data availability.

Auto SCSI ID Selection SCSI ID is automatically set when a drive is inserted into a drive bay.

LED Indicators	LED indicators provide a quick visual assessment of overall system storage status. The MSA30
	has three LEDs in the front, for EMU Status, power and fault. LED status and fault indicators for
	the fans and power supplies are located in the back of the enclosure.

Rack Density	The MSA30 models have a 3U height.

Environment	Each MSA30 model is equipped with a hot-pluggable EMU that constantly monitors the enclosure,
Monitoring Unit (EMU)	the power supplies, and fans to ensure suggested operating tolerances are maintained.
	NOTE: A U320 compatible EMU is required for a U320 I/O module.

Single Bus I/O Module	The single bus I/O module allows one SCSI channel to access all drives in the MSA30.

Dual Bus I/O Module	The dual bus I/O module allows two SCSI channels to access a single MSA30. This allows for
	greater fault tolerance (controller duplexing) or provides access from two different servers to two
	separate storage areas.

Fault Tolerance	With the dual bus I/O module, redundant power supplies and fans, the MSA30 provides a high
	level of system availability. Using an internal or external RAID Array, the MSA30 can be
	configured for RAID levels 0, 1, 1+0, 5 and RAID 6 with ADG when using a HP Smart Array RAID
	controller.

Manageability	Depending on the host controller, the MSA30 is managed by HP Insight Manager or
	StorageWorks Command Console.
