1. Virtunet Systems Elevator Pitch
What We Do
Server Side Performance Tier for Existing SAN
Software Only
How Our Customers Benefit
Increases Application Performance
Increases number of VMs per Host
Pushes out SAN upgrades
Status of Company
9 year old

2. VirtuCache Easy to Manage
Accelerate Storage Performance from ANY SAN based Storage Appliance by Caching frequently used data to in-host SSD.
10 Minute Install
No Agents in Guest VMs
Easy to Manage
No Downtime

3. VirtuCache - Features Accelerates Reads + Writes
Clusters SSDs across Hosts
Mirrors Writes across Hosts
Supports All VMware Advanced Features – DRS, Linked Clones, Snapshots, HA, VDI (View, Xen Desktop), Replication, Stretched SAN Cluster, vGPUs, Instant Clones, FT, etc.

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 $10-20/GB
HBA and SAN Switch Upgrade Reqd
Storage Appliance Needs Replacing
Affordable
Same SSD costs < $1/GB retail.
Reduce Network Burden. No SAN Upgrade
Cost of Entry = Lic Fees + SSD for One Host

5. Versus Hybrid Array and CEPH (Storage connected to 8 hosts)
3-year costs
Higher End Hybrid Arrays (HP Nimble, 3PAR, etc).
RedHat CEPH + SuperMicro.
Virtunet + Cheap Shared SAS Storage e.g. Seagate 5005, Dell PowerVault, HP MSA.

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 higher performing than in the storage appliance since its closer to the CPU.
