A customer has a Symmetrix VMAX storage array configured with 99.9% utilization of raw
storage capacity. The frame is configured with storage pools as shown in the exhibit. Note
the following:
Pool P00400GE00R5 is 400 GB SSD RAID 5
Pool P02002TS72R6 is 2000 GB SATA RAID 6
Pool P01450GF15R1 is 450 GB FC 2-Way-Mir
SRDF/A replication suspends regularly
Investigation shows that write pending values are too high for the R1 volumes. I/O
requirements for the DSE pool are computed. If DSE is used, where and how should the
pool be built?
A.
Drain selected FC TDAT volumes in 80 RAID sets Delete selected FC TDAT volumes
Create 2-way-mir volumes on FC disks for DSE pool
B.
Drain selected SATA TDAT volumes in 10 RAID sets Delete selected SATA TDAT
volumes Create 2-way-mir volumes on SATA disks for DSE pool
C.
Drain selected EFD TDAT volumes in 12 RAID sets Delete selected EFD TDAT volumes
D.
Create 2-way-mir volumes on EFD disks for DSE pool Drain selected FC TDAT volumes
in 80 RAID sets Delete selected FC TDAT volumes Create 3+1 R5 volumes on FC disks for
DSE pool
