Chapter 1 RAID introduction
1.1 Features
i8500 controller features:
•
Front-end 2 GbE NIC ports.
•
iSCSI jumbo frame support.
•
RAID 6, 60 ready.
•
SATA II drives backward-compatible.
•
One logic volume can be shared by as many as 8 hosts and 32
connections per system.
•
Host access control.
•
Configurable N-way mirror for high data protection.
•
On-line volume migration with no system down-time.
•
HDD S.M.A.R.T. enabled for SATA drives.
With proper configuration, i8500 can provide non-stop service with a high degree
of fault tolerance by using i8500 RAID technology and advanced array
management features. The controller features are slightly different between the
backplane solution and cable solution. For more details, please contact your

.
i8500 connects to the host system in iSCSI interface. It can be configured to any
RAID level. i8500 provides reliable data protection for servers and RAID 6. The
RAID 6 allows two HDD failures without producing any impact on the existing
data. Data can be recovered from the existing data and parity drives. (Data can
be recovered from the rest disks/drives.)
Snapshot
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. Snapshot can keep up to 32 snapshots for all data
volumes.
Rollback
feature is provided for restoring the previous-snapshot data
easily while continuously using the volume for further data access. The data
access which includes read/ write is working as usual without any impact to end
users. The snapshot is taken at target side and done by i8500. 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 modification.
i8500 is the most cost-effective disk array controller 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 (SMB) users.
