so I am receiving error 2170 (ms exchange replication slow IO error) on one of my exchange 2010 servers. Nothing has changed in roughly 3 years but these errors just started a week ago. I do have the DBs and logs on the same spindles but it has been that way since it was first put into production. Some mailboxes on the DB receiving the errors are between 20 and 30 GB.
I found several posts pointing to resources. This is a VM. It has (2) 4-core processors and 10 GB RAM. The vSphere client shows 'Consumed Host Memory' at 10318 MB and 'Active Guest Memory' at 1228 MB, give or take a little (I saw it go to 1848 MB or so). Seems like there is plenty of memory. However, when I go to the server and open task manager > performance tab > resource monitor, it shows 85% used physical memory (8774 MB in use, 712 MB standby, and 750 MB free).
All that said, I am going to add RAM I guess, perhaps 2 - 4 GB and see if that alleviates the error since I really can't do anything about the storage / spindles right now.
Any thoughts on the exchange error are appreciated.
If someone could explain to me why the memory shows so much less used in vSphere as compared to within the server's resource monitor itself would be great.
