SCSI or Fibre Attached Direct Attached Storage
with SATA, SAAS or Fibre Fibre drives utilizing the RAID option you desire.
From 8 to 42 drives in a single enclosure
Looking for the fives 9's,NEBS certification,
we can help you?
A
logical drive is simply an array of independent
physical drives. The logical
drive appears to the host the same as a local hard disk drive does.
The
concept of a logical volume is very similar to a logical drive. A logical volume
is composed of one or several logical drives, the member logical drives can be
the same RAID level or different RAID levels. The
logical volume can be divided into a maximum of 8 partitions. During operation,
the host sees a non-partitioned logical volume or a partition of a partitioned
logical volume as one single physical drive. Attach an array of storage to a
server and you have a Direct Attached Storage array.

Management Solutions
NAS -Primarily designed to provide access at the file
level. Organizations working on LANs consider NAS the most economical addition
to storage.
DAS or SAN - Optimized for high-volume block-orientated data
transfers.

DAS: Ideal for Local Data Sharing Requirements
Direct-attached storage, or DAS, is the most basic level of storage, in which
storage devices are part of the host computer, as with drives, or directly
connected to a single server. Network workstations must therefore access the
server in order to connect to the storage device. This is in contrast to
networked storage such as NAS and SAN, which are connected to workstations and
servers over a network. As the first widely popular storage model, DAS products
still comprise a large majority of the installed base of storage systems in
today's IT infrastructures.
Although the implementation of networked storage is growing at a faster rate
than that of direct-attached storage, it is still a viable option by virtue of
being simple to deploy and having a lower initial cost when compared to
networked storage. When considering DAS, it is important to know what your data
availability requirements are. In order for clients on the network to access the
storage device in the DAS model, they must be able to access the server it is
connected to. If the server is down or experiencing problems, it will have a
direct impact on users' ability to store and access data. In addition to storing
and retrieving files, the server also bears the load of processing applications
such as e-mail and databases. Network bottlenecks and slowdowns in data
availability may occur as server bandwidth is consumed by applications,
especially if there is a lot of data being shared from workstation to
workstation.
DAS is ideal for localized file sharing in environments with a single server or
a few servers - for example, small businesses or departments and workgroups that
do not need to share information over long distances or across an enterprise.
Small companies traditionally utilize DAS for file serving and e-mail, while
larger enterprises may leverage DAS in a mixed storage environment that likely
includes NAS and SAN. DAS also offers ease of management and administration in
this scenario, since it can be managed using the network operating system of the
attached server. However, management complexity can escalate quickly with the
addition of new servers, since storage for each server must be administered
separately.
From an economical perspective, the initial investment in direct-attached
storage is cheaper. DAS can also serve as an interim solution for those planning
to migrate to networked storage in the future. For organizations that anticipate
rapid data growth, it is important to keep in mind that DAS is limited in its
scalability.
