NEC Dynamic Pools

• Dynamically add HDD one by one

• Dynamically grow/shrink LUNs in pool

• Capacity immediately available

• No performance hit– Combining metaLUNs is slow

• Performance similar to RAID-5

• “Semi-synchronous”– Asynchronous

replication for medium distances

– Continuous– All writes

• “Background Copy”– Asynchronous for long

distances– Periodic– Workload-based– Only delta changes

• Synchronous – Continuous– All writes– MV & RV in parallel

Performance Management

• PerformanceMonitor– Real-time monitoring and reporting

– Gather performance data for later analysis

– Threshold set/detect for overloads

• PerformanceNavigator– Analysis of accumulated data

– Graphical comparative analysis

• PerformanceOptimizer– Automates data movement

to avoid hot spots

– Can migrate LUNs to other diskpools for storage tiering


More than MAID: PowerConserver

08121228

Massive Arrays of Idle DisksPower down inactive disks – lower power and cooling

Disks can be stopped and started on-demand or periodically to save power

30-60% energy savings in secondary storage applications

More than MAID: Traditional MAID only allows a certain percentage of disks to spin at once. D-series can spin all disks as needed.


More than WORM: Volume Protector
