A Pair of Virtual Technologies to Create True Scale-out Storage Almost three years ago, VMware introduced the world to its virtual SAN. This new solution enabled customers to use storage within ESXi servers without the need for external storage - an exciting promise for organizations that wanted to quickly scale their virtual storage. Now, it's time to check in on this technology and see if it's living up to its promise. VMware became a player in the storage array and software market when it launched vSAN. Server admins were looking forward to using vSAN because it gave them a symmetrical architecture that did not require external storage, thus being able to use storage within existing servers. It also doesn't require specialized storage skills. However, no one solution can be all things to all enterprises, and as enterprises began to deploy vSAN across their enviro... (more)

Solving the Storage Problem | @CloudExpo #IoT #Cloud #BigData #Storage

Web-scale IT is a pattern of global-class computing that delivers the capabilities of large cloud service providers within an enterprise IT setting by reimagining positions across several dimensions. The unprecedented explosion of Big Data and cloud services is driving the development of new storage architectures to store the information produced by this web-scale trend. It is becoming increasingly clear that even a linear growth trajectory for storage is insufficient to deliver the quantity of storage needed for data produced by the Internet of Things. Current architectures have... (more)

The Future Is Now: Why Flash Storage Will Transform the Data Center

For an example of just how dramatically storage has changed over the past fifteen years, consider your music collection. At one point, you had a collection of cassettes that stored the song files on tape. As the years went on, your hairstyle changed and you bought a CD player that used a spinning disk to store more song data at a higher quality than tape could. Spinning disks flourished well into the MP3 player era, surviving even the initial introduction of flash storage due to its competitive cost. Eventually, however, your newest smartphone or iPod shipped with flash storage i... (more)

Beating the Data Deluge | @CloudExpo #NAS #BigData #DataCenter #Storage

Beating the Data Deluge with Scale-Out NAS for Hybrid Cloud IDC estimates that the digital universe is doubling every two years. That means the need for data storage is increasing at the same rate. This exponential demand is no match for traditional vertical-scaling storage architectures. The resulting bottlenecks significantly reduce performance, and trying to store so much data would require prohibitively expensive server scale-out. The reality, though, is that the majority of data centers around the world are still using vertical scaling solutions for storage, which means that... (more)

Virtualization and the Next Generation of Storage Architecture

Legendary Intel co-founder Gordon Moore's eponymous law holds that the number of transistors per square inch of chip will double every two years, a prediction that has held remarkably firm as incredibly tiny devices have been made increasingly powerful. In recent years, that assertion could be used to apply to the creation of data as well. An IDC study in 2011 showed that the amount of data created by every device and person in the world would double every two years, with a staggering 1.8 zettabytes (1 billion terabytes) created in 2011 alone. A significant driver for this trend... (more)
