EMC VNX – RAID groups vs Storage Pools
With EMC training I have learnt some general guidelines, that should be followed to optimize and enable good performance on a VNX Unified storage system.
Drive types
When you chose a specific drive type, you should base your choice upon the expected workload.
FLASH – Extreme Performance Tier – great for extreme performance.
SAS – Performance Tier – perfect for general performance. Usually 10k RPM or 15k RPM.
NL-SAS – Capacity Tier – most cos...

what is FAST Cache?
what is FAST Cache?
You can compare FAST Cache as a “DRAM cache” but built from FLASH drives, with higher capacity available. Let’s start at the beginning:
DRAM cache – is a storage-system component that improves performance by transparently storing data in very fast storage media (DRAM). It’s capacity is limited and very expensive.
FAST cache technology supplements the available storage-system cache (DRAM cache), adding up to 2 TB read/write FAST Cache. The nice trick is that FAST Cache...

EMC VNX FAST VP Definition
EMC VNX FAST VP Definition
FAST VP stands for Fully Automated Storage Tiering for Virtual Pools. It’s a very smart solution for dynamically matching storage requirements with changes in the frequency of data access. FAST VP segregates disk drives into three categories (already explained in EMC VNX – RAID groups vs Storage Pools) called tiers:
Extreme Performance Tier – Flash drives
Performance Tier – 15k and 10k SAS drives
Capacity Tier – Near-line SAS drives (that can be up to 4TB i...
