CHAPTER 3 Supporting Workloads Anytime, Anywhere 31 These materials are © 2020 John Wiley & Sons, Inc. Any dissemination, distribution, or unauthorized use is strictly prohibited. compression. By squashing the amount of data that has to be stored, you don't need as much power and cooling. The nodes themselves are also potential sources of improved datacenter metrics, but this time, the focus goes to workload per- formance. Thanks to the fact that data is close to applications and, at a minimum, accelerated by flash, if not operating on all-flash nodes, you may see reduced latency. Latency is the king of workload performance metrics. Reducing it does good things for your workloads. Supporting Big Data Big data is, well, big! How big? Big in this context can range from a few terabytes to several petabytes. Your next-generation HCI solution must be able to grow with you as your big data needs burgeon. Nutanix next-generation HCI can support your enterprise big data needs with solutions that handle tens of petabytes of data. Big data comes in many forms and requires a variety of storage service to work, from block to file to object storage. Most HCI solutions support running virtual machines (VMs) but only a few, such as Nutanix, also support native file, block, and object storage services. A next-generation HCI solution breaks out of the traditional lim- itation and becomes a platform that provides native storage ser- vices without forcing you to build a VM construct, such as a Server Message Block (SMB) file server. Flash and Next-Generation HCI — Savior of the Universe It was once fashionable to design storage systems around the applications that they would support (and storage architects are, of course, known for their sense of fashion). Actually, designing your storage around applications was required. Hard disk drive
