Employee Retirement Benefit Plans [Abstract]
Employee Retirement Benefit Plans	12. Employee Retirement Benefit Plans *Dot Hill Retirement Savings Plan* The Dot Hill Retirement Savings Plan, which qualifies under Section 401(k) of the IRC, is open to eligible employees over 21 years of age. Under the plan, participating United States employees may defer up to 100% of their pretax salary, but not more than statutory limits. At our discretion we may make contributions to this plan for plan participants. Our matching contributions vest to employees as a percentage based on years of employment from one to five years, and matching contributions are fully vested to employees after five years of employment. Our matching contributions to the retirement savings plan for the years ended December 31, 2009, 2010 and 2011 were $0.2 million, $0.1 million and $0.1 million, respectively.

The entire disclosure for pension and other postretirement benefits.
