INTRODUCTION
• The storage-area network (SAN) is a set of protocols
and technologies that permit storage devices to have
direct connections with servers over some distance.
In addition, a SAN permits the storage devices to be
shared among a number of servers based on select
criteria. Finally, using VSAN technologies (virtual
SAN), a group of discrete SANs can be connected
together using a "virtual" SAN fabric.
WHY SAN?
• The following are some of the business drivers for SAN
deployments:
• • Escalating storage requirements
• • Rising storage management costs
• • Business continuity
• • Requirement to share information
• • Increasing levels of underutilized disk storage resources resulting
in increased backup storage and backup handling costs
• One disadvantage to SANs is that there is limited vendor
interoperability.
ADVANTANGES AND DISADVANTAGES
Advantages Disadvantages
The SAN's performance is directly linked
to that of the type of network being used.
In the case of a fibre channel network, the
bandwidth is approximately 100
megabytes/second (1,000
megabits/second) and can be extended
by increasing the number of access
connections.
It is much more costly to acquire a SAN
than a NAS because it is a complete
architecture that uses technology that is
still very expensive
A SAN's capacity can be extended almost
limitlessly and can reach hundreds and
even thousands of terabytes
Using a Storage Area Network is that it
would be very difficult to keep up your
data if it breaks down.
it is possible to share data between
several network computers without
sacrificing performance because SAN
traffic is completely separate from user
traffic
with regards to stability, functionality and
speed, it's second to none.
SAN COMPONENTS
There are three main components to a SAN
• Host Bus Adapters (HBA)
• Data Storage Devices
• Storage Subsystems
HOST BUS ADAPTER
• An HBA is an I/O adapter that provides connectivity between
a host server and a storage device. The HBA is used to connect
a device to a SAN using a Fibre Channel interface. Intelligent
HBAs perform many of the lower-level I/O functions to
minimize the CPU impact on the host server. HBA connection
methods can be either copper or fiber, similar to a typical LAN
adapter.
DATA STORAGE DEVICES
• Disk drives themselves cannot sit directly on the network. The
technologies listed represent the controller intelligence that enables the
drives to be used. The means needed for physical connectivity may vary.
There are several methods of connecting storage devices to their host
CPUs:
• • Parallel SCSI copper interconnects
• • Optical direct connect
• • Fibre Channel switch
STORAGE SUBSYSTEMS
• Storage Subsystems connect storage devices to the network. Storage
organization can be supported through various subsystems from simplistic
to complex with large volumes of storage and many services available.
Types of storage subsystems are:
➔Just a bunch of disks (JBOD)
➔Storage arrays
➔RAID
RAID OVERVIEW
• RAID is a method used to inexpensively put together a
set of physical hard drives into a logical array of storage
devices. RAID provides fault tolerance compared to
standalone disk drives. RAID does this by mirroring
data or implementing parity check operations. RAID
can be performed using hardware or host-based
software. Several types of RAID can be used, including
one or more of these:
• RAID 0 (striping)
• RAID 1 (mirroring)
• RAID 3 (error detection)
• RAID 5 (error correction)
