@it_user202749 I have to add a few topics to this.Most of all, large block sizes only help in regards of throughput, but not IOPS. The more IOPS you want to get, the smaller the blocks have to be. A modern Flash Array is usually optimized for 32k Blocksize which is the average for regular hypervisor environments. SQL and other databases even use 64k blocksize as default, because of the 8K pagesize with 8 pages per reads.And of course, there are already flash based storage systems on the market where you don´t need to - or even cannot at all - disable dedupe and compression to prevent performance gaps. These two features are essential to increase the lifetime of the flash cells. Variable block sizes for inline dedupe are needed to be effective nowadays.Finally the asynchronous or synchronous replication has to be considered specifically on the workloads to use. Each write needs to travel to the remote site before the commit to the host is send. So the lateny will be higher (round trip time is added to the write latency) for write intensive workloads which can get avoided by using asynch or near synch replication features. The storage should be able to address all possibilities at the same time of course. :-)Not to mention NVMeoF option or Intel Optane technology for the last peak of performance. :-)
