Intelligent Design Delivers Scalability and Upgradeability
Four 3Gb SAS (Serial Attached SCSI) x4 host interface ports per controller provide highly reliable, high-performance, price-conscious primary storage solution for first deployments as well as customers upgrading from a traditional Ultra SCSI 320 storage solution. Choose the E-Class system that fits your requirements today with the confidence that you have the flexibility to change the host interface simply by changing the controllers and also increase your available storage by adding JBOD systems from our VTrak J-Class and scale to meet your future needs. In addition, one of the key advantages of the SAS technology implemented in the VTrak E-Class and J-Class is the ability to connect either SAS or SATA drive with the same interface. This simplifies data management by allowing businesses to easily expand SAS storage as their critical business transactions increase and migrate less-accessed data to SATA storage. Sharing most common FRUs between products also eliminates spare parts SKUs and simplifies field replacement. In addition, with the VTrak E310s there are four SAS ports that will allow you to connect or cascade multiple E310s units without the added cost of a SAS switch

No Single Point of Failure
With the VTrak E310s Promise has dramatically narrowed the gap between simple fault tolerance and No Single Point of Failure. The E310s incorporates an intelligent, enterprise-level, cable-less system design which includes fully redundant, hot-swappable controllers, power and cooling units, which are all field replaceable. All system components are constantly monitored to ensure continuous operation in case of disk failure or a controller, power supply, or cooling unit malfunction. Dual active-active, failover/failback RAID controllers provide redundant data paths to further help ensure availability.  

Comprehensive Data Management
The VTrak E310s features an embedded management software, WebPAM PROe, that eliminates the need to install additional software on the network. All VTrak systems in your network can be configured and monitored through a single, easy-to-manage web-based graphic user interface. The software works through the VTrak systemЎ¦s Ethernet port - locally, across a LAN, or across an internet connection - to configure and monitor one or multiple VTrak system(s) and provide error reporting through pop-up messages, event logging, or email notification. In the event of a controller failure, Promise's management software will also seamlessly failover and failback. The VTrak family also simplifies integration with third-party management applications using industry-standard SNMP and CIM protocols.
