Self-Encrypting Drives (SEDs) are designed to safeguard critical personal and business information
and to comply with Regulatory Mandates
Optional Disk
Enclosures
Just as the user has a choice of chassis for the array head (LFF and SFF drive bays, AC or DC powered), so
also do they have a choice of expansion disk enclosures accommodating either drive size. Both the MSA
2040 and the D2700 disk enclosures can be hot-added to an operating array. SFF and LFF Array heads and
Disk Enclosures can be mixed without limitations.
MSA 2040 3.5-inch Disk Enclosure. This 2U unit has twelve LFF (3.5-inch) drive bays and accepts for MSA
dual-ported SAS, SEDs and SAS MDL drives. The pre-configured HP MSA 2040 LFF Drive Enclosure (C8R18A)
has two I/O modules and supports both single and dual controller arrays.
This 3.5-inch MSA disk enclosure can be attached to MSA 2040 LFF or SFF array head.
Each configured model ships standard with two .5m mini-SAS to mini-SAS cables for connection to
the MSA 2040 array expansion port or existing disk enclosure cascade port.
LFF and/or SFF Disk Enclosures can be mixed up to the maximum of 7 total Disk Enclosures
The MSA 2040 does not support LFF SATA HDDs.
D2700 2.5-inch Disk Enclosure. This 2U storage enclosure (AJ941A) is designed to support twenty five HP
Storage or ProLiant 2.5-inch Universal form factor (SFF) 12Gb, SSD, SAS, SEDs or SAS MDL hard drives. It
ships standard with dual I/O modules installed.
This 2.5-inch D2700 disk enclosure can be attached to MSA 2040 LFF or SFF array head
The D2700 enclosure ships with a two .5m mini-SAS to mini-SAS cables for connection to the MSA
2040 array expansion port or existing disk enclosure cascade port.
LFF and/or SFF Disk Enclosures can be mixed up to the maximum of 7 total Disk Enclosures.
The MSA 2040 does not support SFF SATA HDDs.
Scalability
The MSA 2040 array configurations are designed to allow an installation to begin with smaller capacity and
be able to grow gradually as needed. The flexibility of SSD, 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 72 TB SAS MDL, expandable to 576 TB SAS MDL
with the addition of a maximum of seven MSA 2040 3.5-inch Disk Enclosures.
Small Form Factor configurations can scale from 28.8 TB SAS. With the addition of seven D2700
JBODs, the MSA 2040 storage can support 238TB SAS.
Users may configure a 24-drive MSA 2040 array head with 12-drive LFF MSA 2040 3.5-inch disk
enclosures. This is an excellent option for a configuration that supports high-speed SFF SSDs or
fast SFF enterprise-class SAS drives in the array head, combined with economical LFF drives
staged for archival purposes, all in the same array.
Vdisks
The Vdisk nomenclature is being replaced by Disk Group. In the Linear Storage and in the SMU V2 you will
see reference to Vdisk in Linear Storage and the SMU V3 you will see Disk Group. Vdisk and Disk Group are
essentially the same. Vdisks have additional RAID types (RAID 0, 3) not available only in the CLI.
Disk Group
A Disk Group is a collection of disks in a given redundancy mode (RAID 1, 5, 6, 10, 50). It is equivalent to a
Vdisk in Linear Storage and utilizes the same proven fault tolerant technology used by Linear Storage. Disk
Group RAID level and size can be created based on performance and/or capacity requirements. With GL200
