WORKLOAD SELECTION AND CACHE CAPACITY PLANNING FOR A VIRTUAL STORAGE AREA NETWORK

摘要

Exemplary methods, apparatuses, and systems receive characteristics of a plurality of input/output (I/O) requests from a workload, including logical address distance values between I/O requests and data lengths of the plurality of I/O requests. Based upon the characteristics, a data length value representative of the data lengths of the plurality of I/O requests is determined and an access pattern of the plurality of I/O requests is determined. A notification that the first workload is suitable for a virtual storage area network environment is generated based upon the characteristics. The first workload is selected as suitable in response to determining the data length value for the data lengths of the plurality of I/O requests is less than a data length threshold and/or the access pattern of the plurality of I/O requests is more random than an access pattern threshold on the spectrum from random access to sequential access.

1. A computer-implemented method, comprising:
receiving characteristics of a plurality of input/output (I/O) requests from a first workload, wherein the characteristics include logical address distance values between I/O requests and data lengths of the plurality of I/O requests; determining, based upon the data lengths of the plurality of I/O requests, a data length value representative of the data lengths of the plurality of I/O requests; determining, based upon the logical address distance values of the plurality of I/O requests, an access pattern of the plurality of I/O requests on a spectrum from random access to sequential access; and generating a notification that the first workload is suitable for a virtual storage area network environment based upon the characteristics, wherein the first workload is selected as suitable in response to determining the data length value for the data lengths of the plurality of I/O requests is less than a data length threshold and/or the access pattern of the plurality of I/O requests is more random than an access pattern threshold on the spectrum from random access to sequential access.
