LONGMONT, Colo., May 28, 2013 (GLOBE NEWSWIRE) -- Dot Hill Systems Corp.
(Nasdaq:HILL), a leading provider of SAN storage solutions, today announced it
has been named to UBM Tech Channel's CRN 2013 Virtualization 50 list for the
third year running. The annual listing showcases the companies with the most
innovative virtualization solutions on the market today.

Selected by CRN editors, the 2013 CRN Virtualization 50 recognizes the vendors
that are addressing an emerging market need for the channel and offering the
most innovative solutions. The list is designed to help solution providers
identify and evaluate virtualization products and programs to help grow their
business.

Dot Hill's approach to storage virtualization is centered on an open
architecture based on standard networking protocols, and key features that
create more flexibility and storage performance. Certified for VMware vSphere,
Citrix XenServer and Microsoft Hyper-V, Dot Hill AssuredSAN™ solutions are
well-suited for virtualized and cloud computing environments. Dot Hill

number of highly compelling enterprise-level features, including demonstrated
99.999 percent availability and up to 384TB of data capacity in a single
array.

"Dot Hill continues to make virtualization a key focus in the development of
our AssuredSAN storage solutions," said Jim Jonez, senior director of
marketing, Dot Hill. "Our product portfolio with real-time autonomic tiering
improves the performance of virtualized server applications, including virtual
desktop infrastructure (VDI), under a variety of hypervisors. Our recent SPC-1
benchmark result submission^1 demonstrates 39,041 measured SPC-1 IOPS on
random I/O workloads, outperforming many other technologies. As the storage
virtualization market shifts from server-based solutions to embedded storage
virtualization architectures, Dot Hill will continue to develop cost-effective
virtual storage solutions, equipped with streamlined management features."

technology. However, understanding the diversity of vendors and their solution
nuances can be incredibly daunting," said Robert Faletra, CEO, UBM Tech

innovative technology vendors that are not only delivering powerful
virtualization technology, but also helping VARs capitalize on the market
