Life cycle management of virtualized storage performance

An apparatus for providing life cycle management of memory resources in a data center containing a plurality of virtual machines, comprising:

• a computing system comprising one or more hosts in one or more clusters for hosting the virtual machines;
• at least one non-volatile memory that the virtual machines can write data to and read data from;
• a management server configured to:
• procure one or more storage devices for each virtual machine by, for each virtual machine:
• measuring, by the processor, the total amount of data written and read by the virtual machine over a specified sizing interval;
• calculating a Write working data set that is the total amount of data written to memory by the virtual machine over a specified sizing interval;
• calculating a Read working data set that is the total amount of data accessed by the virtual machine from persistent storage over the sizing interval;
• determining whether the Read working data set is greater than either an actual resource usage by the virtual machine or a size of a virtual disk associated with the virtual machine and, if so, set the Read working data set to be the size of the smaller of the size of the virtual disk or the calculated Read working data set times a hit rate;
• setting a size of a cache resource for writes at a desired margin over the calculated Write data set;
• and
• setting a size of a cache resource for reads at a hit rate times calculated Read data set;
• operate the data center and measure data regarding operating parameters of read and write workflows in the data center;
• and
• analyze the data regarding the operating parameters to identify any bottlenecks in memory accessed by a virtual machine and a network connection between a virtual machine and memory.

A non-transitory computer readable storage medium having embodied thereon instructions for causing a computing device to perform a method of life cycle management of memory resources in a data center containing a plurality of virtual machines running on one or more hosts in one or more clusters, the method comprising:

• procuring, by a processor, one or more storage devices for each virtual machine by, for each virtual machine:
• measuring, by the processor, the total amount of data written and read by the virtual machine over a specified sizing interval;
• calculating, by the processor, a Write working data set that is the total amount of data written to memory by the virtual machine over the specified sizing interval;
• calculating, by the processor, a Read working data set that is the total amount of data accessed by the virtual machine from persistent storage over the sizing interval;
• determining, by the processor, whether the Read working data set is greater than either an actual resource usage by the virtual machine or a size of a virtual disk associated with the virtual machine and, if so, setting the Read working data set to be the size of the smaller of the size of the virtual disk or the calculated Read working data set;
• setting a size of a cache resource for writes at a desired margin over the calculated Write data set;
• and
• setting a size of a cache resource for reads at a hit rate times calculated Read data set;
• operating, by the processor, the data center and measuring data regarding operating parameters of read and write workflows in the data center;
• and
• analyzing, by the processor, the data regarding the operating parameters to identify any bottlenecks in a storage and network configuration of a virtual machine and a network connection between a virtual machine and memory.
