- Snapshot and Rollback
The SA-6643S 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, which 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.
- Online Volume Group, User Data Volume Expansion and RAID Level Migration
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
RAID 6 improves over the industry standard RAID 5 by adding another parity disk which enables greater reliability and data protection.
- 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.
- Link Aggregation or Trunking
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.
- Global or Dedicated cache by volume
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.
- BBU
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.
