Today’s corporate data centers are using more and more compute and storage resources to meet rapidly increasing operational requirements. Because traditional data center architectures are experiencing great difficulty in meeting these new demands, an alternative technology is swiftly gaining acceptance. Hyperconverged Infrastructure, or HCI, is on what Stefanie Chrias, IBM’s VP Power Systems, calls “a rapid growth trajectory.” And now, for the first time, this new technology that is so swiftly penetrating enterprise data centers is available to run on IBM’s Power Systems platforms.
But what, exactly, is hyperconverged infrastructure?
HCI takes the fundamental elements of the data center, servers, data storage, and networking, and packages them together in a single unified appliance. The entire unit, as well as its component parts, is controlled entirely by sophisticated software under the direction of detailed policies established by IT administrators. Both the compute engine and the storage controller run on the same server platform, and each appliance functions as a node in a cluster.
The constituent parts of the HCI appliance are hidden behind a unified “single pane of glass” software interface. So, there is no need for users or applications to deal directly with the hardware or its particular characteristics. The software can automatically and transparently carry out tasks such as performing data backups, scaling out (simply by adding nodes) to provision additional storage as needed, or swapping out nodes that fail. This approach greatly simplifies the IT management task.
Part of the appeal of HCI is that it was designed to run on inexpensive industry-standard x86-compatible servers and storage devices. But that meant IBM’s RISC-based Power Systems line was shut out of this fast-growing market.
HCI and Power Systems
Now, however, IBM has announced that it is partnering with Nutanix, which 451 Research has named as the leading HCI provider, to market appliances based on the Power Systems line rather than x86 servers. Because of the superior compute and data handling capabilities of the Power architecture, IBM believes this new platform will allow enterprise customers to “run any mission critical workload, at any scale, with world-class virtualization and automation capabilities.” The platform is particularly suited to running high performance database, analytics, machine learning, and artificial intelligence applications.
For IBM, HCI is “a fundamentally different approach to enterprise application needs.” It also represents an important emerging market that IBM didn’t want to be left out of.
