Features

Composable Quality of Service

With great power comes great flexibility. VAST’s composable architecture makes it possible to provision the performance of a pool of servers to a set of users or applications to isolate application traffic and ensure a quality of ingress and egress performance.

Overview

The VAST Data Platform for All Workloads

Experienced storage architects will tell you that combining multiple workloads to a single storage platform can lead to poor outcomes – that was true until the VAST Data Platform. Resource contention and  ”noisy neighbors” issues meant that infrastructure teams would deploy many different storage platforms to ensure predictable performance on legacy storage.​

VAST provides the ability to divide and compose multiple different pools of resources giving administrators ultimate flexibility when serving the needs of their users. Now you can deploy one simple pool of flash storage to serve all your workloads with reduced administration and efficiency benefits that compound as your cluster grows.​

How It Works

Flexibility: Powered by DASE™

The VAST Servers in a cluster can be subdivided into Server Pools that create isolated failover domains, making it possible to provision the performance of an arbitrarily-sized pool of servers to a set of users or applications to isolate application traffic and ensure a quality of ingress and egress performance that’s not possible in shared-nothing or shared-disk architectures.

Use Cases for Server Pools:

  • Support different network technologies on a single cluster (ethernet and infiniband) ​

  • Control Access to Data with network-based protection to isolate data sets to designated tenets​

  • Performance Isolation to eliminate “Noisy Neighbor” issues​

  • Optimize resource utilization by scaling of pools via API, adding and removing servers to meet changing needs.

Difference

Server Pools for Composable QoS​

Server pools are key to enabling application consolidation onto one scalable all-flash platform, by provisioning dedicated resources for demanding applications or tenants. Pools can easily be scaled up and down as the needs of applications change, thanks to DASE.
