QuestionQ42

Performance-tune and optimize an existing enterprise HPE Storage solution

You want to increase the deduplication ratio for a client’s MS SQL VM farm hosted on an HPE Alletra Storage MP B10000.

Which step should you take?

Explanation

HPE Alletra Storage MP B10000 uses 16 KiB cache pages for read and write operations. Using guest OS allocation units that are multiples of 16 KiB keeps I/O and data layout aligned with those pages, which improves the array’s ability to identify duplicate blocks across the VM farm. HPE documents that Microsoft SQL Server workloads on this platform support compression and deduplication.
