The Dot Hill AssuredSAN 3000 Series offers support for 8Gb Fibre Channel storage area networks (SANs).
Dot Hill Systems Corp., a
provider of storage area network (SAN) solutions, announced that the most
recent version of its firmware for AssuredSAN 3000 storage systems will include
VMware vStorage APIs for Array Integration (VAAI) support and Site Recovery
Manager (SRM) support, to help improve performance and data security within
VMware virtual server environments.
VAAI includes three separate
capabilities: block zeroing, full copy, and hardware-assisted locking. The
AssuredSAN 3000 supports these functions with the new firmware and can now
speed provisioning of new virtual machines, accelerate cloning and reduce the
use of the CPU for storage vMotion functions. Dot Hill's firmware release
featuring VAAI and SRM support will be available within 30 days. The firmware
upgrade is free to existing AssuredSAN 3000 customers.
SRM is VMware's flagship
product for data protection and disaster recovery across geographic sites. SRM
is integrated with array-based replication to provide an enhanced mechanism for
maintaining replicas of virtual machines on multiple sites. The AssuredSAN 3000
Series, with built-in AssuredRemote technology, provides the replication
element of the overall SRM solution, enabling customers to implement a disaster
recovery plan for their virtual machines.
VMware certifies the VAAI
support on the AssuredSAN 3000 Series on vSphere 4.1 and 5, while the SRM
support on the AssuredSAN 3000 Series is certified by VMware on vSphere 5.
These features are available through a free software upgrade to the AssuredSAN
array and are enabled by a free software plug-in to the VMware ESX servers.
"Customers using VMware
virtualization require high performance and high availability network storage
solutions. Dot Hill's AssuredSAN 3000 series provides a unique combination of
high speed and five 9's of availability," said Jim Jonez, senior director
of marketing for Dot Hill. "The Dot Hill AssuredSAN 3000 array with VAAI
and SRM support improves storage efficiency with added security for VMware
Customers choosing the
AssuredSAN 3000 array can access features, such as advanced data management,
remote replication, snapshots, volume copy, energy-saving drive-spin-down and
Dot Hill's EcoStor green features. Dual redundant RAID controllers, dual power
supplies and dual fans bring uptime figures to higher levels of availability.
The platform leverages VMware's virtual file system and Storage VMotion
technologies to perform proactive, non-disruptive storage migration, eliminate
virtual machine I/O bottlenecks and free up storage capacity.
"While users appreciate
that they can free up server and I/O resources to support virtualized
production workloads by moving I/O-intensive processes from their ESX hosts to
their storage arrays, the actual level of benefit they'll realize from VAAI
will to a large degree depend on the underlying storage, said Mark Peters,
senior analyst with IT research firm Enterprise Strategy Group. Flexible,
scalable, high-performance storage systems with VAAI integration will logically
allow customers to gain more efficiencies, increase consolidation and,
therefore, reap greater returns on their VMware investments."
The AssuredSAN 3000 Series
offers support for 8G bit Fibre Channel SANs, dual interface 8G bit Fibre
Channel/1G bit iSCSI and 6G bit SAS-attached JBODs, along with optional Dot
Hill AssuredRemote data management software for remote replication. Advanced
data management, such as AssuredCopy and Dot Hill's volume copy technology
enable the creation of independent data volume copies for additional data
protection. It also incorporates a number of eco-friendly features such as
drive-spin-down capability and 595-watt 80 PLUS-rated power supplies.
Additionally, the arrays feature EcoStor "green" battery-free
alternative for cache memory, which leverages a combination of super capacitors
and flash memory that outlasts traditional batteries.
