A Customer Has a VSP G800 Storage System with an HDT

A customer has a VSP G800 storage system with an HDT pool with internal SAS drives and a virtualized third-party array using SATA RAID 6. The virtualized array is connected to the VSP G800 using four 8 Gbps FC paths. The customer reports performance problems on an OLTP application deployed on a virtualized server using the HDT pool. What are two reasons for this problem? (Choose two.)

A) The workload includes significant random writes to SATA over RAID 6.
B) The tier relocation is not assisting the OLTP application.
C) The size of Tier 1 is not sufficient to accumulate all of the hot pages.
D) The speed of the FC links is insufficient.
