I can’t imagine there is anything he does not know. We plan to continue to work with him on a regular basis and continue to enjoy the benefits on his knowledge.

Doing this exposed all of the wasteful IO practices they had in their SQL environment.

Additionally, he made several other recommendations and configuration changes that had a significant positive impact on database performance.

Whole experience was excellent from start to finish.

SQL Server Replication - expert and professional assistance. My whole experience was excellent from start to finish. Red9 was willing to accept a job that was a bit outside of normal, in that what I was really looking for was someone to provide some expert advice to a novice SQL Server admin. I needed some pointed training in replication best practices and performance tuning. I understand that teaching is quite a different skill set than actually performing the tasks yourself, so Red9's ability to convey his points clearly and tailor them to my level of understanding was impressive. Red9 was also responsive to my request for a follow-up, and did a very good job communicating when setting up meeting times. I would not hesitate to recommend Red9 to anyone who has a need for expert and professional assistance with SQL Server. My whole experience was excellent from start to finish.

Win Server 2008R blowing 53 error suddenly

Mark is UNBELIEVABLE! We had a server connection issue plaguing us for over 3 weeks. We had 2 so-called professionals trying to figure out what the problem was, and after 3 weeks they were still scratching their heads! I hired Mark to investigate this issue. Within ONE HOUR Mark honed-in on the actual problem; advised us on what needed to be done with the Server Hosting company, and then within 30 minutes we finally had access the crucial data we needed to run our business! Anyone looking for a TRUE professional regarding SQL or SQL Server, don't even bother looking elsewhere; Mark is the exactly the guy you want and need!
