Customers that have transitioned or plan to transition to HCI state cost reduction, accelerated deployment, improved ability to scale, improved operational efficiencies and reduction in infrastructure tasks as top benefits they expect to realize when implementing HCI.
HCI delivers a compelling story for both CapEx and OpEx.
Savings in initial investments are lower, and operational expenses are also lower when compared to traditional three-tier architectures. Cost savings include power and cooling, ongoing system administration, and the elimination of disruptive upgrades and data migrations.
Rather than buying monolithic SAN-based infrastructure, a business can buy infrastructure that targeted for specific workloads. A main contributor to lower TCO and the increased agility of hyperconverged solutions is the ability start smaller and scale incrementally.
Not only is initial CapEx investment lower, but you can also scale them more incrementally, adding smaller amounts of compute or even expanding just the storage capacity as required, as shown in the figure below.

Further, some HCI systems support multiple nodes in a single chassis. So, if space is available, you can simply plug a node into an existing chassis in a matter of minutes to scale your infrastructure. Deploying HCI reduces time, risk and complexity.
The following figure shows how HCI simplifies IT management and operations as compared to a traditional SAN environment.

The most compelling HCI solutions leverage management frameworks that drastically improve operational tasks, reduce the burdens of lifecycle management, and improve the level of responsiveness of IT staff to meet the needs of their business. Ideally, existing investments in management and orchestration stacks can be leveraged as well.
