Us vs. SAN and Appliance Upgrade
SAN and Storage Appliance Upgrade
Virtunet
Higher Latency
Lower Latency
• SSDs behind Controller and Network
• SSD closer to CPU
• Only 2 Controllers (CPUs) involved in
Caching
• 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
Affordable
• Storage Vendor SSDs cost $20-40/GB
• Same SSD costs $1-3/GB retail.
• HBA and SAN Switch Upgrade Reqd
• Reduce Network Burden. No SAN Upgrade
• Storage Appliance Needs Replacing
• Cost of Entry = Lic Fees + SSD for One Host

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