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

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

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.

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

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.

Summary 1 : Separation of Capacity and Performance Best done with centralized storage Performance Best done closest to the CPU

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.
