This Exabyte 215 Mammoth-2 tape library ships with one M2 tape drive installed and is able to accomodate up to two M2 tape drives and 15 SmartClean AME data cartridges. MEDIA IS NOT INCLUDED. When populated with two M2 tape drives and 15 225m SmartClean data cartridges the 215 has a native capacity of 900 GB (2.25 TB compressed) and can back up 86.4 GB/hour native (216 GB/hour compressed). The 215 is black in color and ships in a compact desktop configuration (one cubic foot) and is also rackmountable in a standard 19" rack using the optional rackmount kit (DP - 967741). When rackmounted the unit takes up just five units of rack height and two 215 units can be mounted side-by-side which maximizes valuable data center space. The M2 tape drives are designed to be field replaceable, allowing for ease of service and the ability to upgrade to future-generation tape drives, further protecting the user's investment. The Exabyte 215 tape library is designed for users in IT environments who need high-capacity, cost-effective data storage and fast access to their data in a compact form factor.
