Data is growing exponentially and it is becoming more
and more critical to make this data available online 24x7.
Traditionally, a single server with a few GBs of disk was
sufficient but with the growth in the storage environments
and the data, the traditionally methods are no more being
easily accepted.
Enterprise Storage could be done in three major forms.
Data could be stored on external disk boxes directly attached
to the servers. This system of storage is referred to as
Direct Attach Storage. Available in both SCSI & Fibre Channel
Connection to a disk array which offers a wide choice of
using SCSI, Fibre as well as ATA drives depending on the
performance vs. cost preference. A portion of the complete
storage can be allocated to different servers depending on
the requirement. DAS is preferred for a network of 2 to 4
servers.Data could be stored on external disk boxes directly

When heterogeneous servers are available on the network and
cannot be connected directly to a common storage, it becomes
difficult to add on disk space on each server. To protect your
investment, we have Network Attached Storage solutions
available with us. NAS offers optimum utilization of
resources and instant backups on a backup device directly
connected to the NAS appliance. Depending on the customer’s
current and future storage requirements, NAS can be used as
Integrated NAS as well as
Gateway NAS.
For a large no. of heterogeneous servers requiring high
performance and online transaction processing,
Storage Area Network
is the best choice. Most SAN implementations
are based on the Fibre Channel architecture.
Fibre channel
is a technology standard that allows data to transfer from
one node to another at very high speeds of 1 Gb/s to 2 Gb/s.
iSCSI is the latest technological implementation for SAN.
It is an open standard based approach by which SCSI
transports are wrapped by TCP/IP to allow their transport
over IP.
With the developing technologies, NAS and SAN convergence is
the latest trends in operation these days. SAN implementations
are done through a
NAS gateway. This helps utilizing the same
disk system for both NAS-centric as well as SAN-centric
applications.
To meet the latest high availability demands, we offer solutions
integrating NAS, SAN and CAS to provide the optimum storage.
