I have a Dell PowerVault NV3100 as our centralized NAS running Windows Storage Server 2008R2 with the latest patches and updates. As the NAS, it hosts our file shares, our network Home Folders (with folder redirection), Group Policy software pushes, and our Roaming Profile (not large since we are redirecting folders to the network Home Folders). Ever since we ran this setup, everything has been fine for the 2 years since upgrading to this equipment... Until recently these past few months...
High memory utilization (server has 6GB) after a few days of running the server. Occasionally users who try to log on to our AD, they will be hung up on the "Welcome" screen for MINUTES, not seconds... Sometimes as bad as 25 minutes (remember, romaing profiles, home directories, folder redirection all being run from this file server). Refusing network connections... The only thing to alleviate this issue is to reboot the entire file server and the clients who experienced the 'forever' log in times.
Something has defintely changed these past few months, because these issues never happened before. The file server got rebooted every month for 'Patch Tuesdays' but is seems to be rebooted more frequently to alleviate high memory usage, and login/network access issues.
Does anyone have a clue what's going on? What's causing this? Dynamic Cache? Using RAMMap to empty sets (only works as a temp workaround)? Help, please! ~_~
