What's New in Firmware 1.2.0
 
In every generation of firmware, SANOS continues evolving and keeps advancing on the enterprise features, friendly user 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. And also supports SSD endurance, IOPS performance, iSCSI mutual CHAP …etc. Lots of WebUI operations are enhanced.
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 level and different quantity of disk. 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 administrator to arrange storage plan flexibly.

SSD Endurance
 
SSD (Solid State Drive) is getting 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 of SSD is. The system will notify user if the SSD endurance is under 10%. And also 5%, 3%, 2% by sequence.

System IOPS & Volume Performance Monitoring
 
Add system IOPS performance in Dashboard and volume IOPS/Throughput performance in Monitoring page. These will help users to monitor and analyze the performance. And then make the appropriate adjustments.
iSCSI Mutual CHAP
 
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.
