What's New in Firmware 1.2.0
In every generation of firmware, SANOS continues to evolve and advance on the enterprise features, user-friendly interface design, and performance improvement. In this newer version, firmware 1.2.0, we support auto tiering 2.0 with flexible RAID and disk configurations. Also supported is SSD endurance, IOPS performance, iSCSI mutual CHAP, etc. Lastly, we've enhanced the WebUI operations.
Auto Tiering (QTiering 2.0)
Auto Tiering 2.0 supports flexible RAID and disk configurations. You can create each tier (disk group) with different RAID levels and quantity of disks. For example, SSD tier uses 4 disks with RAID 10 for extreme performance, SAS tier uses 6 disks with RAID 6, and NL-SAS tier uses 8 disks with RAID 5 for capacity. This feature is very important for IT administrators to arrange storage plans flexibly.

SSD Endurance
SSD (Solid State Drive) is growing more popular but its disadvantage is having a limited write cycle. We provide an SSD endurance value to monitor the health of SSDs. The value is a percentage to know how much remaining life the SSD has. The system will notify the user if the SSD endurance is under 10%, 5%, 3%, and 2% by sequence.
System IOPS & Volume Performance Monitoring
Add system IOPS performance to the Dashboard and volume IOPS/Throughput performance to the Monitoring page. These will help users monitor and analyze performance, allowing them to adjust appropriately.
CHAP (Challenge Handshake Authentication Protocol) is a type of authentication in which the authentication server sends the client a key to be used for encrypting the username and password. It enables the username and password to transmit in an encrypted form for protection. Besides, mutual CHAP is a two-way authentication between the iSCSI target and the initiator. User has to enter another username and password which are set in the initiator side.
And More...
Besides, there are lots of enhancements for WebUI displays and operations. Fore more information, please refer to the firmware 1.2.0 release note and the XCubeSAN SANOS 4.0 User’s Manual.
