High Availability,The Promise VTrak E-Class is a family of intelligent dual-controller SAS/SATA-based storage arrays that fundamentally changes storage economics, from purchasing and configuration to operation and upgrades. Two 4Gb Fibre Channel (FC) host interface ports per controller provide connectivity to widely deployed Fibre Channel storage networks, perfect for complementing existing storage networks or creating new ones. Each standard 19" 3U rack unit supports up to 16 standard 3.5" 3Gb/s SAS or SATA drives. Connect up to four SAS JBODs in daisy chain to provide over 80 network storage bays.4G Fibre Channel Performance and ReliabilitySAN technology has revolutionised the way data flows in the enterprise. VTrak E-Class joins this revolution by exceeding the performance and bandwidth requirements of the most data-intensive applications. The flexible and mature Fibre Channel technology and its broad interoperability make it the first choice for critical applications.No Single Point of FailureThis enterprise-class cableless system design includes fully redundant and hot-swappable controllers, power and cooling units. All system components are constantly monitored using standard protocols to ensure continuous operation in the event of component failure or malfunction. Dual active-active RAID controllers, with failover/failback, provide redundant data paths to help further ensure availability.RAID 6RAID 6 (dual parity) offers the highest level of reliability and data protection in a cost-effective solution. As storage array capacity increases, the risk of encountering unrecoverable read errors with single-parity RAID levels also increases. RAID 6 can handle two disk failures, providing greater protection against data loss. This also significantly reduces the risk of catastrophic data loss during RAID reconstructions.Easy to Install and ManageThe VTrak range integrates Promise's browser-based management interface, WebPAM PROe, eliminating the need to install additional software. All VTrak systems on the network can be configured and monitored using a single, easy-to-manage interface via an out-of-band Ethernet port. Using standard management protocols, Promise simplifies integration with third-party management applications.Service and SupportEach VTrak is covered by Promise's 3-year limited warranty with 24/7 telephone and email support (Americas & EMEA). When our support confirms an on-site failure, advance replacement parts are always available to eliminate downtime.
