Single choice
Customer added three new servers to an existing SAN consisting of two fabrics. Each fabric consists of two switches with two ISLs. This change negatively impacted performance. Throughput is as follows: 20MB/s on Host HBAs at 4K block size 50MB/s on Symmetrix on the FA ports 60MB/s on each ISL port The physical disks are 80% utilized but with 100% cache-hit ratio.
What should the customer do to improve performance?
