HP MSA 1040 E7W00A 사용자 설명서

installed.

This 2.5-inch D2700 disk enclosure can be attached to an MSA 1040 (SFF or LFF) array head
The D2700 enclosure ships standard with two .5m mini-SAS to mini-SAS cables for cascading to other
disk enclosures
Up to three D2700 may be attached to the MSA 1040 array head, providing support for up to 99 SFF
drives.

The MSA 1040 Arrays are designed to allow an installation to begin with smaller capacity and be able to
grow gradually as needed. The flexibility of SAS or SAS MDL drives 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 48 TB SAS MDL, expandable to 192 TB SAS MDL with
the addition of a maximum of three MSA 2040 3.5-inch Disk Enclosures.
Small Form Factor configurations can scale from 28 TB SAS. With the addition of three D2700 JBODs,
the MSA 1040 storage can support 118 TB SAS.

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.

The MSA 1040 Arrays support 512 volumes and up to 512 snapshots in a system. All of these volumes can
be mapped to LUNs. LUN sizes up to 128 TB depending on the disk and RAID configuration chosen. The array
supports expansion and deletion of any LUN.

In addition to the usual RAID levels, the MSA 1040 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. 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.

The preliminary performance figures provided here are for your reference as many variables exist between
array configurations, workloads, hard drive types, vdisk setup parameters and host system setup.
