Open-E: Admin Settings, iSCSI, And Fail-Over
Apart from its typical storage management menus, Open-E DSS 6.0 also has menus that allow you to control access to the server itself.
You can restrict Web-based GUI access to one particular IP address.
Connections to the server can be secured by TLS, SSL v3, or a combination. You can obtain usage statistics like server load and network traffic via SNMP, and then graph them with RRDTOOL.
In addition to the Web GUI, password-protected console access via SSH is also available.
Open-E DSS 6.0 can not only serve as an iSCSI target, but also an iSCSI initiator, facilitating storage expansion.
If a server is mission-critical, availability becomes an even more important consideration than even performance. Downtime is simply not acceptable. Because hardware defects are almost impossible to anticipate, enterprises typically employ redundancy in those mission-critical environments. Thecus addresses this to the best of its ability, employing redundant power supplies and, of course, support for RAID modes that withstand one or two drive failures.
But what if the appliance's memory goes out, or maybe its RAID controller? Open-E DSS 6.0 has a built-in fail-over mechanism able to designate a primary and a secondary node. In the event of a hardware failure, the redundant node automatically assumes the primary server's role, and service continues uninterrupted without intervention. Then, with slightly less urgency, the failed node can be replaced with a working system, which then becomes a redundant secondary.
