Thanks, Jamen,
Yes, tier-ing within a server using PCI flash can improve performance of certain workloads by pinning hot tables/files or using it as high speed temp storage.
In addition there is a “very hot” tier with all flash, (hot, warm and cold in between), and a “colder or a close to frozen” tier with cloud using Cisco ICF – stay tuned for the solution/demo at Cisco Live San Diego.
