Mfg. Model Number:
Promise VTrak VTE310sD
Features and Benefits:
With an eye on enterprise features at a price that even a small to medium businesses can afford, the Promise VTrak E-Class fundamentally changes storage economics from purchase and set up to operation and upgrades. The flexibility to use Serial Attached SCSI (SAS) and Serial ATA (SATA) drives and the open architecture of the VTrak E-Class lets businesses use the components that are best suited to their application needs. All of the systems in the E-Class series also share the same firmware for ease of qualification. Promise's WebPAM® PROe provides an OS independent, centralized GUI for comprehensive data management.
