Warm-up Question: Intro to Information Lifecycle Management
We're going to start introducing discussion questions from the ISM book on a regular basis. This question is from Chapter 1, and should be a warm up question for most of you.
To participate, add a comment to this discussion with your answer. Extra points if you provide a diagram of your solution!
Warm-up Question: Intro to Information Lifecycle Management
An engineering design department of a large company maintains over 600,000 engineering drawings that its designers access and reuse in their current projects. These documents are modified or updated as required. The design team wants instant access to the drawings for its current projects, but the current infrastructure cannot scale to meet the response time requirements.
The team classifies the documents as:
- Most Frequently Accessed
- Frequently Accessed
- Occasionally Accessed
- Archive.
Describe an ILM solution that would optimize the company's storage infrastructure and satisfy the response time requirements. You get to decide the existing storage infrastructure and if it should be updated or replaced.
For this exercise, cost is not a concern. The only requirement is to justify all of your suggestions.

Well since these are engineering drawings then RAID3 would give best performance for the buck to stream these large files. So the differentiating factor may come down to drive type or array type.
For a single storage array environment then having different drives would be the ideal way of doing things.
Most Frequently Accessed - on EFD drives in a 4+1 RAID3 set
Frequently Accessed - on 15k RPM drives in a 4+1 RAID3 set
Occasionally Accessed - on 10k RPM drives in a 4+1 RAID3 set
Archive - on SATA drive on EFD drives in a 8+1 RAID3 set
F.A.S.T. would be the perfect solution for a customer in this single array scenario
If I was to use different EMC arrays then I'd be looking at:
Most Frequently Accessed on a V-Max using EFD drives
Frequently Accessed on a Clariion CX4 15k RPM drives
Occasionally Accessed on a the same Clariion CX4 10k RPM drives
Archive - I'd employ a Centera for that work.
