Virtualization has become the de facto standard for the majority of enterprise applications, but most management tools cannot provide virtual machine (VM) level visibility and control over input/output (I/O) performance and other capabilities such as replication. Steve Phillips, Principal Systems Engineer with Tintri by Data Direct Networks (DDN), recently joined George Crump, Lead Analyst for Storage Switzerland, to discuss a new approach to optimizing storage capacity and performance as well as data services on a VM-specific basis.
Whereas many storage management tools look solely at storage hardware or storage volumes, the Tintri Global Center (TGC) management tool understands granularly each VM’s unique requirements (I/O performance levels, backup and replication needs, etc.), and enables the storage device to respond automatically. Most notably, it can automatically adjust queue depths (the number of pending I/O requests for a given storage volume at a specific point in time) to avoid a particularly performance-hungry workload from impacting other workloads in the environment (also known as the “noisy neighbor” problem). The result to the customer is better responsiveness to dynamic application requirements, better utilization of resources across the infrastructure stack, and a streamlined path to identifying and resolving application performance issues.
