Chapter 1 Introduction
The
iSCSI RAID Subsystem
Host systems can connect to the iSCSI RAID subsystem using iSCSI protocol. The
iSCSI RAID subsystem can be configured to any RAID level. The iSCSI RAID subsystem
provides reliable data protection for servers and the
RAID 6
function is available. The
RAID 6 function allows two HDD failures without any impact on the existing data. Data
can be recovered from the remaining data and parity drives. (Data can be recovered
from the rest disks/drives.)
Snapshot-on-the-box
is a fully usable copy of a defined collection of data that
contains an image of the data as it appeared at the point in time, which means a point-
in-time data replication. It provides consistent and instant copies of data volumes
without any system downtime. The iSCSI RAID subsystem’s snapshot-on-the-box can
keep up to 32 snapshots for each data volumes.
Rollback
feature is provided for
restoring the previously-snapshot data easily while continuously using the volume for
further data access. The data access is regular as usual including read/write without
any impact to end users. The "on-the-box" terminology implies that it does not require
any proprietary agents installed at host side. The snapshot is taken at target side and
done by iSCSI RAID controller. It will not consume any host CPU time thus the server
is dedicated to the specific or other application. The snapshot copies can be taken
manually or by schedule every hour or every day, depends on the settings.
The iSCSI RAID subsystem is the most cost-effective disk array subsystem with
completely integrated high-performance and data-protection capabilities which meet or
exceed the highest industry standards, and the best data solution for small/medium
business users.
