Family Information
Page 8
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 and SAS MDL drives. Each pre-configured HPE MSA 2040 LFF Disk Enclosure
(M0S96A) has two I/O modules.
• This 3.5-inch MSA disk enclosure can be attached to either an MSA 1040 LFF or SFF array
head.
• Each disk enclosure ships standard with two .5m mini-SAS to mini-
SAS cables for cascading to
other disk enclosures
• Up to three MSA 2040 3.5-inch disk enclosures can be attached to an MSA 1040 Array.
D2700 2.5-inch Disk Enclosure. This 2U storage enclosure (AJ941A) is designed to support twenty
five HPE Storage or ProLiant 2.5-inch SFF 6Gb SAS 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 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.
Scalability
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 120 TB SAS MDL, expandable to 480 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 43.2 TB SAS. With the addition of three
D2700 JBODs, the MSA 1040 storage can support 178.2 TB SAS.
Vdisks
Disk Group
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 the Virtual 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) available only
in the CLI.
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 or newer firmware multiple Disk Groups can be allocated into a Storage
Pool for use with the Virtual Storage features.
LUNs
Storage Pools
The MSA 1040 arrays support 512 volumes and up to 512 snapshots in a system. All of these
volumes can be mapped to LUNs. Maximum LUN sizes up to 140TB (128TiB), the LUNs size are
dependent on the storage architecture: Linear vs. Virtualized. Thin Provisioning allows the user to
create the LUNs independent of the physical storage.
The GL200 firmware or newer introduces Storage Pools – which are comprised of one or more Disk
Groups. LUNs are no longer be restricted to a single Vdisk as with Linear Storage. A volume’s data on a
given LUN can now span all disk drives in a pool. When capacity is added to a system, users will
benefit from the performance of all spindles in that pool.
Leveraging Storage Pools, the MSA 2040 supports large, flexible Volumes with sizes up to 128Ti
B and
facilitates seamless capacity expansion. As volumes are expanded data automatically reflows to
balance capacity utilization on all drives.
