Janus 6643 16 bay SATA II to iSCSI RAID

Description

These bundles include a Janus6643 SATA II-iSCSI unit with choice of four drive sizes, five-year warranty, iSCSI interface card, & a maintenance kit that contains a drive, a drive tray, a power supply, & fan. Memory upgrades and battery backup units are also available - please contact your RaidWeb representative for more details.

The JanusRAID SA-6643S is a single controller, iSCSI to SATA-II RAID system. It features a compact 3U - 16 bay chassis, 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 a java-based web browser which allows 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 Janus 6643 contains the following built-in functions:

• Snapshot and Rollback: The Janus6643S implements a Copy-on-Write snapshot technology 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.
• SCSI Enclosure Services (SES) management This feature allows users to communicate using an iSCSI initiator to the RAID subsystem to monitor voltages, temperature, and other diagnostic information.
• MPIO and MC/S Ready: 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.
• CHAP Authentication 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.

The Janus 6643 is the perfect solution for anyone who needs large amounts of network data storage while maintaining high data transfer rate and compact rack space.
