Why each option
To meet the customer's requirements for 4TB performance data and 24TB archive data on a two-node HP 3PAR StoreServ 7400, a configuration focusing on 10k RPM drives provides a balanced and cost-effective solution.
Mixing 15k and NL drives might introduce complexity in tiering for a dual-purpose workload and might not offer the best overall performance-to-price ratio without advanced tiering software.
Only 8 x 100GB SSDs is likely insufficient for 4TB of performance data, and the high proportion of NL drives focuses heavily on archive without adequately addressing the performance data's needs.
A configuration with 4 SFF shelves and 52 x 900GB 10k drives provides sufficient raw capacity (46.8TB) to accommodate both performance and archive data requirements while offering consistent performance and simplified management through the use of a single drive type.
Eight 100GB SSDs are too small for 4TB of performance data, and 98 x 450GB 10k drives, while providing capacity, might not be the most cost-effective or balanced choice compared to larger 900GB drives for the given requirements.
