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
© Copyright 2017 Dell Inc.27
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
