SA-6643S
The JanusRAID
SA-6643S is Arena MaxTronic entry into the enterprise iSCSI market. The
SA-6643S features an Intel IOP331processor, in a compact 3U - 16bay 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 SA-6643S is a single
controller, iSCSI to SATA-II RAID system. In a compact 3U - 16 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 SA-6643S 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.
