The CPU to HDD Performance Gap CPU Improves 100 Times Every Decade – Disk Speed Hasn’t
100 Times Improved
10,000 Times Improved FLASH
2000 2010 2020
MOORE’S LAW CPU Continue To Improve While Disk Drive Performance Remains Flat. As A Result, Applications Will Increasingly Be IO-bound Unless We Rapidly Move To FLASH.

Multi-Core RAID Performance Scale with Advanced Availability and Flexibility
Permanent Sparing – Any unused drive is a potential hot spare – 3 Policies:
▪ Recommended ▪ No Hot Spares ▪ Custom
Portable Drives – No slot to drive location dependency – Drives can be relocated between busses, shelves
etc.
Bus 2, Enclosure 0
Bus 0, Enclosure 0
RAID group 1
RAID group 2 VAULT
* CLI available to copy spare back to replaced drive

Multi-Core Cache Performance, Efficiency and Ease-of-Use Benefits
Performance improvements based on: – Modularization of cache engine
▪ Delivers seamless performance, scales with cores ▪ Supports large write cache sizes (close to maximum
DRAM size)
– One large, shared cache
– Adaptive cache management and improved cache algorithms
▪ Adjusts to changing IO profiles ▪ Write cache re-use after flush ▪ Improved pre-fetch
15 © Copyright 2013 EMC Corporation. All rights reserved.
Improved Performance and Efficiency of FAST Cache Multi-Core FAST Cache
Performance enhancements – New Stack Order
▪ Reduced cache hit pass-through overhead – Increased promotion queue – Proactive clean optimization
▪ Improved responsiveness as promotions are not delayed by flush of dirty pages
– Faster initial warm-up ▪ Single hit incurs promotion until FAST
Cache is 80% full.

FAST Cache Configuration • FAST Cache supported for all VNX platforms
– Applicable to VNX for File and VNX for Block
• Highly scalable – Up to 4.2 TB FAST Cache – Supports Reads and Writes
• Applies to classic LUNs and pool LUNs – Thick and Thin pool LUNs
• A system-wide resource that benefits many workloads
– Host application data: OLTP – Oracle + Microsoft SQL, VMware, etc.
– Array-based data services: Snapshots, etc.
• Easy configuration in Unisphere

FAST Cache – Caches from HDD or NL-HDD tiers to
FAST Cache SSDs at 64K page granularity
FAST VP – Dynamically moves data between FAST
VP SSDs, HDD, and NL-HDD tiers at slice granularity of 256 MB
Deploying both together ensures maximum IO granularity

VNX Block Deduplication • Deduplication of data at 8KB
granularity – Deduped LUNs are Thin LUNs
• Settable per pool LUN – Thick, Thin and Deduped LUNs supported
in a single pool
• Freed up blocks/slices are available for re-use within storage pool
• Deduplication occurs out of band to minimize I/O impact
• Considerations: – Fully supported with FAST VP and
replication technologies – Block deduplication not supported for
file or concurrently with compression
