My ramblings about all things technical

Safe and Legit Storage Design

4 Comments

In my previous posting I created a fictitious company who requires you as the VMware Architect to design them a vSphere 5.0 environment to meet all their requirements whilst keeping within their constraints and mitigating risks. Now I didn’t list the constraints or the risks as I felt this was something that is very important to learn how to define in preparation for the VCAP5-DCD and vSphere designs in real life practice.

The first portion of the design I’m hoping to create (and get everyone’s opinions,participation and comments on ) is the storage design. So below are the portions I will be trying to fill out for the Safe and Legit scenario and hopefully people also wanting to learn and participate will fill out each of the sections with their own design decisions and then we can compare and hopefully learn together/off each other.

Storage Array

Design Choice

Number of LUNs and LUN sizes

Storage load balancing and availability

VMware vSphere VMFS or RDM

Host zoning

Thick or Thin disks

Virtual Machine I/O Priority

Storage Profiles

Describe and diagram the logical design

Attribute Specification
Storage Type
Number of Storage Processors
Number of Fibre Channel Switches (if any)
Number of ports per host per switch
Total number of LUNs
LUN Sizes
VMFS datastores per LUN

Describe and diagram the physical design

Array vendor and model
Type of array
VMware ESXi host multipathing policy
Min/Max speed rating of storage switch ports

Loads of bits to decide and design. I’m hoping to have my storage design decisions and what I thought were the constraints and risks for the design up by the end of the week and if not then by the latest next week Monday in my next posting. Happy designing Winking smile

  2. I’ll be covering a number of these in my architectural decisions registers on my blog in coming weeks. 🙂

    • Awesome =0) I’m looking to reference yours among others of decision and thoughts around each design decision. Would love your contribution to this scenario as to have a VCDX give input would help me and I’m certain loads of others learn

  3. When I get a moment I’ll get stuck into getting a few more example ADs done and posted.
