Computing: DataCore's Storage Hypervisor - An Overview –Part 1: New Release Features

A storage
hypervisor is an emerging term used by some vendors to describe their approach
to storage virtualization.
Several companies offer storage hypervisors, including IBM, Virsto and DataCore.
I've already written about IBM and Virsto in previous blogs.
Now it's
DataCore's turn. DataCore is an independent software vendor (ISV), so it has no
financial interest in selling the underlying storage hardware. It supports both
virtualized servers and traditional physical hosts and legacy storage with the
same feature stack and automation. DataCore's storage hypervisor is a software
product called the SANsymphony-V. This blog will examine some enhanced and new
features of the version 9 release.
Auto-tiering
Auto-tiering is a "hot" topic (pun intended!) with not only tier-0 solid state
devices, but also performance (SAS or FC) hard disk drives, capacity (SATA), and
archived storage that can even be rented from public cloud providers at a
distance. This feature also includes automatic tuning that creates heat maps to
reveal heavy disk activity, so that the hottest data gets the most attention (in
order to meet performance service level requirements). It also automates load
balancing across the available disk resources.

Network
Computing: DataCore's Storage Hypervisor - An Overview –Part 2: Two Customer Use
Cases
Host.net is
a service provider that offers VM and enterprise storage platforms in multiple
virtual private data centers (i.e., Host.net hosts customer compute and storage
resources at its data centers) that are all connected to a Cisco-based10Gbps
multinational backbone. Among the many services the company offers are virtual
enterprise servers, storage, backup/restore, disaster recovery and colocation.
DataCore is
at the heart of Host.net's enterprise SAN storage platform. Host.net believes
DataCore offers the necessary performance and data integrity (every byte of data
is written twice within a synchronous mirror) at a competitive price. Among the
things Host.net likes about DataCore are hardware independence (for example, in
a SAN hardware refresh it can add and migrate data on the fly with no downtime),
operating system independence and robust I/O performance, as DataCore's use of
hundreds of gigabytes of high-speed cache essentially turns a traditional SAN
into a high-speed hybrid solid-state SAN at a fraction of the cost.
X-IO
(formerly Xiotech) builds hardware with its Hyper ISE (Intelligent Storage
Elements) storage system. With a great deal of engineering experience and
innovation, the goal is to deliver high performance to accelerate enterprise
applications at good price/performance level. However, X-IO has decided to shed
itself of the storage and data management software (such as snapshot and
replication software) that typically characterizes enterprise-class storage.
But
customers still need storage and data management software. DataCore comes
provides those capabilities in X-IO products. As a result, X-IO can take a
hardware-intensive focus and improve price/performance while DataCore picks up
the slack.
