What single storage system design would provide the best performance and reduce floor space?

An organization plans on building their own cloud solution and is designing a new storage environment with the following requirements:

• Current IOPS = 25,000

• Expected growth rate = 100%

Storage vendor specifications:

• Max storage blocks in a storage system = 8

• Max number of drives per storage block = 24

• Max IOPS per HDD drive = 180

• Max IOPS per SSD drive = 450

What single storage system design would provide the best performance and reduce floor space?
A . 4 SSD storage blocks and 4 HDD storage blocks
B . 6 SSD storage blocks
C . 1 SSD storage block and 6 HDD storage blocks
D . 8 HDD storage blocks

Answer: B

Explanation:

Current IOPs= 25.000

Expected grown 100 %

Required IOPs = 25.000 + 25.000 = 50.000

Capacity of each block with SDD= 450 IOPs x 24 number of drives= 10.800 IOPs.

Capacity of each storage system = 10.800 x 8 max storage blocks in storage = 86.400 for 50.000  10.800 x

To experience better response times of the applications with reduced floor space, it is recommended to use flash drives.
