StorageShort: The Problems with IOPS Testing

When IT professionals begin investigating all-flash arrays they are often drawn to the IOPS benchmark that almost every vendor uses to boast about system performance. The reality is that IOPS, while it may have some value, should be just one of the criteria that organizations should use to determine the best all-flash storage solution for their specific use case. 93 more words

Hyperconverged Flash - Scaling

Scale Computing Briefing Note

There are generally three ways one can use flash in a storage system. From a data management perspective, the all-flash array is the easy approach as one does not need to decide what will go on flash and what will go on disk. 562 more words

Formula to calculate Disk throughput, IOPS, and MBps

IOPS = Throughput/IO (all value in kb)
or
IOPS=*1024
or
IOPS = (MBps Throughput / KB per IO) * 1024
So here is the calculation I was using: 186 more words
