CUSTOMIZABLE VIRTUAL DISK ALLOCATION FOR BIG DATA WORKLOAD

摘要

An example method to allocate a virtual disk for a virtual machine in a virtualized computing system includes allocating a plurality of virtual machine disk file (VMDK) candidates in a virtual machine file system (VMFS) volume, selecting a subset of VMDK candidates from the plurality of VMDK candidates for having performance scores indicative of higher I/O throughputs associated with the one or more physical hard disks than rest of the plurality of VMDK candidates, and configuring the virtual disk based on the subset of the VMDK candidates. The VMFS volume is supported by one or more physical hard disks in a storage system in the virtualized computing system.

1. A system configured to allocate a virtual disk for a virtual machine (VM), the system comprising a processor, a storage system, and a memory coupled with the processor, wherein the memory is configured to provide the processor with instructions for:
allocating a plurality of virtual machine disk file (VMDK) candidates in a virtual machine file system (VMFS) volume, wherein the VMFS volume is supported by one or more physical hard disks in the storage system; selecting a subset of VMDK candidates from the plurality of VMDK candidates for having performance scores indicative of higher I/O throughputs associated with the one or more physical hard disks than rest of the plurality of VMDK candidates; and configuring the virtual disk based on the subset of the VMDK candidates.
