SS-4503S
The
JanusRAID II SS-4503Sis Arena MaxTronic entry into the enterprise iSCSI
market. The SS-4503S features an Intel IOP342processor, in a compact 2U -
12bay chassis, with modularlized fans, power supplies, and controller.
Configuration and monitoring is performed using a java enabled web browser for
easy and simple integration into any environment.
The JanusRAID II SS-4503S is a single controller, iSCSI to SAS
RAID system. In a compact 2U - 12 bay chassis, featuring
hot-swappable power supplies and fans. The RAID controller, fans,
and power supplies are modularized allowing for easy removal from
the rear of the unit. System setup is simple using web
browser allowing easy remote configuration and monitoring.
Copy-on-Write snapshot functionality is built into the controller
to help protect your data.

iSCSI protocol uses TCP/IP to transfer data, which only
requires an ethernet interface, and enables easy integration into
your current network infrastructure. iSCSI encapsulates SCSI
commands and data into TCP/IP packets to transfer through a
ethernet network. By using TCP/IP to transfer ensures that the
transmission is successful, and provides a reliable means of
transfering data. Also, by using your current network
infrastructure reduces the total cost of ownership.

The SS-4503S implements a is Copy-on-Write snapshot technology implemented
that utilizes a small pre-designated volume for the snapshot, known as the
snapshot UDV. When the snapshot is initially setup, metadata, or a table of
contents, of the original volume is copied, and thus makes the snapshot
instantaneous. Before new data is written the original data is copied to the
snapshot UDV, and the new data is written to the original data blocks. In
the event of file corruption, accidental overwriting, or a virus infection,
a rollback can be performed to restore any remaining original data.
Volume Groups can be easily expanded using built-in GUI utilities, allowing
your storage requirements to grow when your needs grow. Likewise, User Data
Volumes (UDV) can be expanded online. A unique feature to the SA-6643S is
RAID level migration, which allows you to upgrade, or downgrade, RAID levels
online.
RAID 6 improves over the industry standard RAID 5 by adding another parity
disk which enables greater reliability and data protection.
This feature allows users to communicate using an iSCSI initiator to the
RAID subsystem to monitor voltages, temperature, and other diagnostic
information.
Multipath I/O and Multiple Connection per session use physical paths to
create logical paths between the host and storage device. If a physical path
were to fail, the multipath software will use an alternate path to the
storage device to enable users continued access to their data.
Challenge Handshake Authorization Protocol, or CHAP, is a powerful
authentication method used for point-to-point user login. When using CHAP,
the server will send an authentication key to the client for encrypting the
username and password. By using the CHAP authentication, the user login
process will be encrypted and secure.
Link Aggregation Control Protocol (LACP), part of IEEE 802.32ad, allows
users to bind together both Ethernet ports of the SA-6643S into a single
logical channel to increase bandwidth. Trunking uses similar binding
methods, combining both Ethernet ports as a single logical port, can
increase the bandwidth as well.
Controller cache can be configured as Global or Dedicated for specific
volumes. This function provides users the ability to dedicate more cache
resources to a mission-critical volume to enable higher performance and
reliability.
An optional BBU can be included in the RAID system to ensure data integrity
in the event of a power outage. The BBU, or battery backup unit, will
provide power to the on-board cache of the RAID controller in the event of a
power outage. This will allow any data that is still stored on the cache to
be saved until power is restored. Once power is restored, the RAID
controller will flush the cache to drives.
