What makes an organization a SMB?
Common Misconceptions of SMB
SMB Specific Considerations
Storage Solutions for SMB
Local Storage vs Shared
VSA vs Dedicated Physical
Design Considerations for the VSA

Mixed definitions exist of what small and medium sizes business are.
From the Vendor perspective, it may be based upon employee size, budgets, purchases, or other factors.
From the organizations perspective it may be based upon their current size or future plans for growth.

They don’t have as large as budgets as bigger companies
As Steve Herrod, CTO of VMware stated during VMworld ½ of the world’s IT budgets are from Small and Medium sized businesses.
They don’t require ‘enterprise class’ features.
Their infrastructures are not as redundant or capable as larger companies.

Group Discussed Considerations
Agility
ROI
Design Changes during design phase
Design must be self sufficient
May not require some of the features
Closer relationship with C-level stakeholders

Storage Solutions for SMB
Local Storage vs Shared
VSA vs Dedicated Physical

Shared Storage
VMotion Requirement
HA
Price has dropped
Local Storage
Free ESXi
No need for VMotion or HA
Remote Sites
Less Complex
Does company have a lot of data? Or high performing workloads?
Local Storage vs. Shared Storage

VSA
Openfiler (no hcl)
Nexenta(no hcl)
Freenas(no hcl)
Starwind(iscsionly,hcl 4.1 only)
Dedicated Physical Storage
Ease of administration
Expandability
Cost vs Performance
Dedicated Physical Storage vs Virtual Storage

Design Considerations for the VSA

Crookston Farms has requested a solution to assist them in the upgrade of their existing 7 physical servers.
All of the hardware they are currently using is not on the HCL for vSphere 5
They have purchased 2 brand new hosts that are on the HCL for vSphere 5
After talking further they like the idea of a shared storage model. They like the simplicity of HA in the event of a host failure if the price is right.
A capacity planner is run and reveals that they can consolidate all 7 of their physical servers onto one vSphere host if necessary.

How much storage is already in the servers?
Are the existing physical server 64 bit capable to deploy vCenter on?
What are the RTO/RPO requirements?
Are there remote replication requirements?
How much money do they have to spend?
What are the requirements for ease of management?
How much storage do they require in total?
VSA Design Scenario

VSA Design Constraints
Host must have:
6 GB Memory minimum with 24 GB recommended
4 NICs
Minimum of 4 disks and maximum of 8 per host(internal disks only, no DAS)
Disks must be configured in a RAID 1/0.
NFS ONLY
Network Overhead for replication
vSphere 5 ONLY
vCenter cannot be part of the VSA cluster.
