I'm running SQL Server 2014 Standard. The SAN is an SSD disk array.
For the last couple days, I've been having IO issues - disk read / writes maxing out randomly. Applications and the SQL Server itself become extremely sluggish and freeze up at times.
I'm getting many of these SQL Log warnings as well:
SQL Server has encountered 1 occurrence(s) of I/O requests taking longer than 15 seconds to complete on file [C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\DATA\templog.ldf] in database id 2
Performance Monitor tracking Avg. Disk sec/Transfer, Disk Bytes/sec, Disk Transfers/sec and Resource Monitor are all over the place. Disk utilization seems to just randomly max out at times.
Thought I'd try posting this before calling Microsoft support. Is this an indication of a hardware issue, SQL issue, database fragmentation? Just not sure where to start with this.
