We are thinking about replacing these storage hosts with one solution, maybe a storage array with appropriate disk space and I/O capacity. What are pros and cons of that solution? Do storage arrays have appropriate I/O capacity (X*software RAID)? Does it scale good? Does storage capacity also scale good in those solutions?
those questions are all extremely vague. 'storage arrays' vs 'storage hosts' could mean almost anything. without a thorough analysis of your workloads, its impossible to guess what your performance or capacity requirements are.
