Summary
This paper studied of (SAN, iSCSI protocol)
and investigates about possibility, using
storage technology of the SANs, and iSCSI-
SAN protocol, to improve access to attached
storage disks storages in local system, with
using iSCSI-SANs as virtual storage, is
rather than DAS storage, in local system.
Where explains the results of experiment is
that improving throughput of iSCSI-SANs in
terms of (I/Os, MB/s), and average response
time in different block sizes of the (I/O)
request, were better than attached storage
disks storages as DAS in local system. This
means that use iSCSI-SANs in local system
as attaché storage disks storages as DAS ,
was become possible, without cost , high
performance, easy control, and allow for use
of all a traditional DAS at a fraction of the cost
, without complexity and effort as SAN. The
SCVM applications, allow for conversion DAS
storage to an SAN storage as virtual machine
are accessed by machines using iSCSI-SAN
protocol. Thus, The iSCSI-SANs technology
is well suitable to implement the SAN, until in
system of PC same.
Abstract
iSCSI is a newly emerging protocol with the goal of implementing the Storage Area Network (SAN) technology over TCP/IP, where enables to access to remote data that in attached storage disks storages - Direct Attached Storage(DAS) over IP-networked. Also it's brings economy and convenience whereas it also raises performance and reliability issues.This paper investigates about possibility , using storage technology of the SANs, and iSCSI-SAN protocol, to improve access to attached storage disks storages in local system, with using iSCSI-SANs as virtual storage, is rather than DAS storage in local system of PC. Explicates after experiment procedure is that improving throughput of iSCSI-SANs was better than attached storage disks storages - DAS in local system . This means is that it can use iSCSI-SANs in local system of PC as attache storage disks storages as DAS , where was become fact not possible, without cost , high performance, and easy control.
