vCAT 3.0 - Architecture to Implementation
Ben Lin, Global vCloud Specialist, VMware, Inc.

2. 2
What is vCAT ?
 Intended for technical architects with a solid foundation of vSphere and
infrastructure knowledge.
 Provides design guidance and examples to build, operate, and consume a
VMware based cloud
 Targeted solution intended to help technical architects to get the information
they need quickly and efficiently.

Storage Design Pattern
You have been hired to design a VMware based private cloud for a
software development company.
The customer is currently in discussions with their storage vendor on
pricing and protocols for a new storage array to accommodate the cloud
workloads.
Provide the initial storage requirements and logical design.

6. 6
Step 1: Assess
Current State
 Average storage capacity for typical workloads?
 What are the application I/O profiles?
 Are multiple of tiers of storage needed?
 Are there existing SLAs for storage performance?
 Project budget?
 Preferred storage vendor?
 Preferred storage protocol?
 Can existing storage be used?

7. 7
Service Requirements
 Single tier of service for storage and compute
 Accommodate up to 500 virtual machines averaging 60GB
Guest OS and Data Storage.
 Flexible way to control or ensure storage performance.
 Expected concurrent powered on VM’s is 50%
 Minimize the capacity and cost of storage
 Constraints
 Existing storage vendor
 NFS preference
 Minimal vCloud experience
