What is Hyperconverged Infrastructure?

Hyperconverged infrastructure (HCI) is scale-out, software-defined infrastructure that converges core data services on flash-accelerated, industry-standard servers, delivering flexible and powerful building blocks under unified management. 

With hyperconverged infrastructure, all key data center functions run in a tightly integrated software layer, simplifying the delivery of services that previously required purpose-built hardware.

 

Hyperconverged infrastructure consists of three software components: compute virtualization, storage virtualization, and management. The virtualization software abstracts and pools the underlying resources and dynamically allocates them to applications running in virtual machines or containers. Users enjoy a sleek new operational model where they manage the compute, storage, and networking from a single tool. Advanced management features further reduce manual tasks or help automate entire operations.

Hyperconverged Infrastructure Overview

Benefits of Hyperconverged vs. Traditional Three-Tier Infrastructure

Operational Simplicity

Before hyperconvergence, IT leaders needed to procure compute resources (servers) and storage resources (external storage arrays) separately. Each component required siloed operational expertise, and management utilized highly manual processes. Hyperconverged infrastructure reduces operational costs with a tightly-integrated hardware and software solution that eliminates the complexities associated with fiber channel networks, purpose-built storage, and complex LUN planning. A single, converged IT team can now monitor and manage the compute and storage resources in less time, freeing personnel to focus on other strategic priorities.

Lower TCO

Today, organizations purchase storage arrays with up to five years of capacity. In addition, external storage arrays require expensive, purpose-built networking for peak performance. Hyperconverged infrastructure lowers CAPEX by using a scale-up/scale-out architecture with industry-standard x86 servers. IT can buy the compute and storage they need for a short period of time and add capacity as needed, either by adding storage drives to existing nodes (scale-up) or nodes to a cluster (scale-out).

Greater Agility

Hyperconverged infrastructure delivers day 0 support for the latest technologies, providing the agility to increase application performance, from business-critical applications to VDI, without a major infrastructure change. Because of the flash-accelerated capabilities of hyperconverged infrastructure, VDI and cloud-native applications are common workloads due to their need for high-throughput, low latency storage that scales out. Business-critical applications, such as relational databases, have become the primary use case for hyperconverged infrastructure.

Customer Stories

iGov uses vSAN to deliver innovative HCI at the edge

iGov Uses vSAN to Deliver Innovative Hyperconverged Infrastructure at the Edge

“We almost fell out of our chairs when we saw the performance from this tiny little server running vSAN. It was staggering. The numbers we got were just unbelievable.” – Tom Lynott, Software Engineering Manager

Wachter lowers storage costs by 80% with vSAN

Wachter Lowers Storage Costs by 80% with vSAN

“Most of the traditional SAN options would have given us 15 to 20 terabytes at a cost of somewhere between $5 and $7 a gigabyte. With the new Cisco servers and vSAN we got cost savings at the rate of 1/5th of the traditional SAN, with 45 terabytes that cost less than $1.50 a gigabyte. It was a massive difference.” – Carl Shriver, IT Operations
