The modular design of the PowerVault MD1120 direct attached storage array is engineered for easy expansion - giving
you more room to store data from your server. Up to six PowerVault MD1120 24 -drive
expansion enclosures can be connected to a dual port PERC6/E giving you between 24 and
144 disk drives options. To keep management simple the PowerVault MD1120 connects to and can be
controlled by a single PERC 6/E RAID controller equipped PowerEdge server. Configure the
specific combination of storage resources you need now, and add more storage volume
later, quickly and easily.
Don't sacrifice capacity for performance, the PowerVault MD1120 now supports the new 7.2K RPM 500GB* SAS makes it ideal for customers who need performance but can’t sacrifice capacities.
2.5" SAS Drives for Performance
The PowerVault MD1120 is Dell's first storage array to feature 2.5-inch SAS
drive technology that consume 70% less space and use up to 50% less power than the 3.5"
drives. Now with 500GB* Nearline SAS drives, there is no need to trade performance for capacity. The PowerVault MD1120 supports up to 12TB of data per enclosure. When configured with SAS disk drives, the PowerVault MD1120 RAID storage array can deliver
the speed, performance and reliability to satisfy mainstream and demanding single
server applications such as email or database applications that store active and
frequently changing information. SAS specifies a transfer rate of 3.0 Gbps (300 MB/sec)
for each drive on the channel to help provide these high levels of performance.
The hot-swappable technology of the PowerVault MD 1120 allows you to remove and replace
drives even when your system is operating, no need to turn it off, and no need to reboot - new
drives are available right away. The unique combination Small Form Factor SAS drive technology
and high spindle count in one modular form gives the PowerVault MD1120 it's edge over the MD1000
for fast access storage when your applications needs it.
The small form factor of the PowerVault MD1120 helps manage power, heat, and space consumption in your
data center. In fact, 2.5" disks consume up to 50% less power and 70% less space than 3.5" drives.
Additionally, the MD1120 uses high-efficiency power supplies and variable speed, temperature controlled
fans to help minimize power consumption.
PERC RAID Controller
The PowerVault MD1120 leverages the PERC RAID controller with the best available in-class PCI Express
interface, offering excellent performance for enterprise. The configuration of the PERC RAID controller
enables the software to recognize the entire array as a single unit, regardless of how many disks you
have activated for storage in the array, helping to increase reliability and fault tolerance. With the
PERC 6/E customers can choose the RAID option that supports their application. The PERC 6/E supports RAID
levels 0, 1, 5, 6, 10, 50 and 60.
Dell PowerVault storage is engineered to work optimally with Dell PowerEdge servers. Dell OpenManageTM
Storage Manager Software can manage both the external array and internal storage within the server itself.
Streamlining storage management through a single, common interface helps reduce resource load on the system,
and is easier to navigate for the user as well.
