SUBMISSIONS FOR ROUND 1 (Closed!)
7. (More Coming Soon)
This design decision works around some fairly strict constraints, such as no >2TB LUNs, no IP based storage & the inability for monitoring solution to be customized.
While the decision is ultimately fairly straight forward, the decision documents the issue well and justifies the decision and discusses in depth the implications of the decision.
This is an example of a fairly obvious decision (considering the constraints) but shows even where a decision may be obvious, or the only option, that understanding the implications is important. Documenting even obvious decisions is also important so in the event of movement within the team, the solution can be understood by people not involved in the original design process.
RUNNER UP ROUND ONE: TSM backup configuration for PureFlex environment? By Ash Simpson @Yipikaye1
Not unlike Chris Jones’ decision, Ash’s submission works within the constraints of an existing environment, where hardware and software has already been purchased. This is a common issue, where Hardware / Software is purchased before a detailed design phase. This is a huge problem in the industry and I encourage you all to ensure this trend does not continue. Without a detailed design phase, it is not possible to confirm what hardware/software is required, as such hardware/software should only be purchased after the design to completed.
Again this decision is fairly obvious given the constraints, but the decision explains the benefits of this method of configuration and discusses the implications which is important.
The constraints did not list anything preventing purchasing of a different backup solution, although this is somewhat implied by the assumptions.
Thank you to everyone who submitted design decisions, and I encourage you all to submit new decisions for Round 2 and am looking forward to new competition participants.
