NEW QUESTION # 160
A storage administrator has a Dell Unity XT 480 system with one pool of flash drives, 192 GB of RAM, and
1.2 TB of FAST Cache.
What is the total cache availability for caching the flash drives?
- A. 1.39 TB
- B. I6.0 TB
- C. 3.58 TB
- D. 3.2 TB
Answer: C
Explanation:
Explanation
The total cache availability for caching the flash drives on a Dell Unity XT 480 system with one pool of flash drives, 192 GB of RAM, and 1.2 TB of FAST Cache is 3.58 TB. This is calculated by adding the system memory (RAM), the FAST Cache, and the pool cache. The system memory is 192 GB, which is equivalent to
0.18 TB. The FAST Cache is 1.2 TB, which is a dedicated cache for the flash drives. The pool cache is 2.2 TB, which is a portion of the flash drives that is reserved for caching the pool data. Therefore, the total cache availability is 0.18 + 1.2 + 2.2 = 3.58 TB.
