Data Storage Solution:
Expertise in both NAS and SAN based storage
technology
NAS: works best for these types of applications: File
serving File
sharing Users'
home directories Content
archiving Metadata
directories E-mail
repositories, such as
enterprise .PST files GRID
computing (using 10 Gigabit
Ethernet) Peer-to-peer
data sharing
SAN: works best for these types of applications: Databases Server
clustering Messaging
applications Backup Data
replication GRID
computing Data
warehousing Recovery
archives Any
application that requires
low latency and high bandwidth
for data movement. These
low-latency networks allow
large blocks of data to
move very fast from computers
to storage, with speeds
up to 400 megabytes per
second
Cross-mirroring data (two systems)
SATA (serial advanced technology attached)
- low in cost, high in density, and
ideally suited for large, sequential data such as backup
and GIS image data
transactions
FC (Fibre Channel) - allows data to be
transmitted and received at one gigabit
per second simultaneously delivering high service levels
but at a greater cost. SAS
(Serial attached
SCSI) - Data
backup and Redundancy
RAID Redundancy
for improved reliability RAID
(Redundant array
of inexpensive disks)
functionality RAID
is a way of storing
the same data in
different places
on multiple hard
disk. Data
mirroring or duplication An
array of multiple disks accessed
in parallel will give greater
throughput
than a single disk Data
striping, for improved performance Redundant
data on multiple disks provides
fault-tolerant Redundancy
for improved reliability RAID
