What data storage virtualization looks like today

Data storage virtualization comes in many different forms today -- most of which give administrators features beyond simply aggregating capacity.


Today's storage virtualization looks very different than it used to.

Storage virtualization aggregates capacity in a given environment under a software layer, which allows capacity to be centrally managed and often provides additional storage features. Storage virtualization isn't new -- vendors such as DataCore with SANsymphony, IBM with its SAN Volume Controller (now rebranded as IBM Spectrum) and Hitachi Data Systems with its arrays have been aggregating capacity for years. But some analysts and IT professionals would argue that the types of data storage virtualization currently available do more than simply pool capacity.

Two examples are software-defined storage -- a technology based on storage virtualization, but that often gives storage other value-added features -- and hyper-converged storage. While the main allure of hyper-convergence is easy deployment and management because components are shipped preconfigured, data storage virtualization is at work inside many systems. A final example is vSphere Virtual Volumes, a young technology that allows administrators to reserve capacity with specified performance and a feature set to which virtual machines (VMs) can be automatically provisioned.

This guide offers an in-depth look at some of the newest types of storage virtualization and their benefits, and will help you to determine whether these technologies are right for your environment.

1Getting started-

The data storage virtualization low-down

Storage virtualization can take different forms, but, at a basic level, its function is to abstract capacity from underlying hardware. There are several advantages to using the technology. First, aggregating capacity means better use can be made of available space. Second, performance can be drastically improved. Additionally, data storage virtualization can allow for more flexible disaster recovery.


Virtualization unlocks the benefits of pooled data storage capacity

At the most basic level, all types of storage virtualization aggregate hardware storage capacity to allow administrators to reduce overhead and improve management. Continue Reading

2SDS aggregation-

The software-defined storage approach

From VMware VSAN to DataCore SANsymphony, many vendors offer what they label software-defined storage (SDS) products. The problem: The definition of software-defined storage isn't so cut and dry. What we do know is that most SDS products use software to pool capacity and to surface the underlying features of storage arrays. To many analysts, that's one of the most popular types of storage virtualization today.


Software-defined storage is on the rise

The software-defined storage market is catching on, but complexity issues are keeping pure SDS from being as prevalent as it could be. Continue Reading


SDS products are more than just software

When too much attention is paid to the software aspect of SDS over its other benefits, the technology can get lost in the data storage virtualization shuffle. Continue Reading


Software-defined storage doesn't lessen hardware's role

Software-defined storage products are supposed to be the answer to tightly linked hardware-software combos that lock into specific vendors. But are they? Continue Reading


Examining the differences between SDS and data storage virtualization

Storage virtualization and software-defined storage can both pool capacity, but SDS may be able to add more value to your environment. Continue Reading


Software-defined storage gains traction

A survey shows that more than 40% of respondents virtualize at least some of their storage, but the rest express some concerns. Continue Reading


Hyper-converged infrastructure and virtualization

Hyper-converged systems package storage, compute, networking and virtualization in one box. Many IT professionals look at hyper-convergence as a way to ease deployment and management in their data centers. But hyper-converged systems are based on the same abstraction as storage virtualization -- the software is abstracted from the hardware to allow for the ease of management and provisioning that users enjoy.

Is the debate over the definition of hyper-converged infrastructure confusing? Take a look at your workloads and how evolving HCI products can fit your needs. Continue Reading


Converging storage and virtualization draws benefits

Hyper-converged systems offer administrators speedy deployment, centralized management and a way to save on operational costs. Continue Reading


How storage vendors paved the way for hyper-convergence

According to analyst George Crump, data storage virtualization vendors were the first to use technology that is the basis for hyper-converged systems today. Continue Reading


What hyper-converged infrastructure really is

Hyper-convergence means that storage, virtualization, networking and compute can be sold in one unit with software providing an overall management layer. Continue Reading

Using hyper-converged software as the basis of a DIY HCI platform can bring great benefits to the right kind of IT operation. But before choosing to go down the self-built HCI path, you need to consider costs, support and implementation. Continue Reading


Virtual Volumes as a form of virtualization

Virtual Volumes (VVOLs) are a vSphere 6 feature many observers consider one of the newest types of data storage virtualization technology. VVOLs allow capacity to be aggregated into what can be thought of as containers to which VMs can be matched based on the amount of capacity and performance they need. By doing so, virtual volumes have created a much more efficient way to provision storage in virtual environments.


VVOLs adoption is ready to grow after not meeting hype

After a slow start on the market, are VVOLs ready to finally meet initial expectations? To understand VMware VVOLS adoption, evaluate risk-averse companies and their high hopes for the technology. Continue Reading
