Unisphere 8.4 Resource View


Updated VMAX capacity reportingClarifying temporary capacity with compression active

• Example of 150TB written– 2:1 compressible– 100TB of usable flash

• Current reporting (5977.9XX)– Compressed and temp (hot) combined

• Updated reporting (5977.10XX)– Separates out temporarily used capacity


VMAX Adaptive Compression differentiationMaintain performance while reducing cost

• Skip compression of hottest data– >80% of IOPS on hottest 20% of capacity

• Writes are cached, then compressed

• Keep host data together (128k track)– Optimal data placement– Keeps all ‘locality of reference’ performance– Large block bandwidth

• Optimized thin pools by compressed size– Each pool has uniform compressed size (8k to 128k)– No garbage collection or additional reserved pool space
