"Expanding the capacity options for the XLS-812300 lets customers buy the storage they need today while giving them the assurance that the system can expand as their data grows. Easy expansion and greater flexibility means that the XLS-812300 delivers even more value to customers needing enterprise features without enterprise costs," said William Gervais, Qualstar president and CEO.

Each MEM ll delivers 535 tape storage slots in just 5.3 square feet of floor space. Using LTO 4 tape technology with typical compression, a single MEM ll holds 856 terabytes, one of the highest storage densities in the industry. One or two MEM ll's can be added to each XLS-812300 Library System, raising its total capacity to 1,365 slots, or 2.2 petabytes of data. XLS-812300 libraries hold up to twelve LTO 4 tape drives, delivering data throughput rates of over 5 terabytes per hour to meet ever-narrowing backup windows.

Adding capacity or drives is readily accomplished in the field with minimal interruption to on-going operations. The MEM ll can be intermixed with the XLS-812300 Expansion Pods to provide granular solutions to meet a broad range of data protection and archival storage growth requirements.
