4. Us vs. SAN and Appliance Upgrade
SAN and Storage Appliance Upgrade
Virtunet
Higher Latency
SSDs behind Controller and Network
Only 2 Controllers (CPUs) involved in Caching
Lower Latency
SSD closer to CPU
Each VMware Host CPU involved in Caching
Throw Away Older SAN and Storage Appliance
Keep Existing SAN and Storage Appliance
H/W Vendor Lock-In – SSDs bought from Storage Vendor
No Vendor Lock-In – SSDs bought Retail
Needs Downtime
No Reboot Even.
Expensive
Storage Vendor SSDs cost $20-40/GB
HBA and SAN Switch Upgrade Reqd
Storage Appliance Needs Replacing
Affordable
Same SSD costs $1-3/GB retail.
Reduce Network Burden. No SAN Upgrade
Cost of Entry = Lic Fees + SSD for One Host

6. Summary 1 : Separation of Capacity and Performance
Best Done with Centralized Storage
Performance
Best Done Closest to the CPU

7. Summary 2 : Cheap and Lower Latency than Alternative
In-server SSD is cheaper than Storage Appliance side SSD.
Deployment of SSD inside the Server is architecturally superior than in the Storage Appliance since its closer to the CPU.
