Virtual SAN

Virtual SAN Puts The App In Charge• Simpler and Automated Storage Management Through Application-

centric Approach

14

Today

1. Pre-define storage configurations

2. Pre-allocate static bins

3. Expose pre-allocated bins

4. Select appropriate bin

5. Consume from pre-allocated bin

1. Define storage policy

2. Apply policy at VM creation

Resource and data service are automatically provisioned and maintained.

Datastore✖ Overprovisioning

(Better safe than sorry!)

✖ Wasted resources, wasted time

✖ Frequent data migrations

� No overprovisioning

� Less resources, less time

� Easy to change

• Compared to external storage at scale

• Estimated based on 2013 street pricing, Capex (includes storage hardware + Software License costs)

• Additional savings come from reduced Opex through automation

• Virtual SAN configuration: 9 VMs per core, with 40GB per VM, 2 copies for availability and 10% SSD for performance

Running a Google-like Datacenter• Modular infrastructure. Break-Replace Operations

28

"From a break fix perspective, I think there's a huge difference in what needs to be done when a piece of hardware fails. I can have anyone on my team go back and replace a 1U or 2U servers. … essentially modularizing my datacenter and delivering a true Software-Defined Storage architecture ."
