M2500 Specifications


     For more information :


The ATL M2500 provides modular scalability for companies that need a storage solution that can grow with their backup requirements. Considering its greatest density per rack, the ATL M2500 packs data capacities into 23.5 inches of rack space.

Developed with flexibility in mind (and based on the ATL M1500), the ATL M2500 can be sized to fit the needs of the workgroup, the remote site, or the enterprise datacenter. The scalability of the ATL M-Series (both ATL M1500 and ATL M2500) is unrivaled since the library does not have to be rebuilt, shipped back to the manufacturer, or taken off-line in order to add modules. The ATL M2500 will change the way you think of "big iron".


  • Base-library configurable from zero to six drives and 100 cartridge slots
  • Scalable via StackLink from one to 18 drives (up to 1.03TB/hour native performance) and up to 300 cartridge slots (48TB native capacity) all "seen" by the backup software package as a single library
  • Supports DLT8000, SDLT220, SDLT320 and LTOTM UltriumTM tape drives
  • Barcode reader standard
  • Data cartridges in removable magazines providing 100% bulk loading and unloading
  • Intuitive GUI control panel SCSI standard with a native fibre library optionOptional remote monitoring, management and SNMP agent (MC300 option)
  • Optional redundant power supplies
  • Intermixable scalability with the ATL M1500
  • Add, remove and replace modules in a StackLinked configuration while modules stay on-line (pass-thru independent of individual modules)
  • Driveless configuration available for "capacity-only" scalability
  • Available in stand-alone (non-rackmountable, desktop) configuration
  • Standard 5x9xNext Business Day warranty
  • Enterprise-class library at an entry-level price!
