AI generated answer (using internal Slack threads):

NetSuite's service tier structure is primarily based on three factors: the number of users, the number of monthly transaction lines, and file cabinet storage. If your account exceeds the limit on any of these three factors, NetSuite may require you to upgrade to the next service tier. There are different service tiers offered by NetSuite, such as the Standard and Premium tiers. The Standard service tier, for example, supports up to 200,000 monthly transaction lines. If this limit is exceeded, you may be required to upgrade to the next tier at your next renewal. In terms of determining whether you are on a shared or dedicated server in NetSuite, it's important to note that the service tier is what primarily determines the resources you receive. You can find more information about this in the NetSuite online help documentation. If you find that you're using too much storage, one way to reduce this is by deleting files from your file cabinet. However, you should only do this if you're certain you won't need these files in the future. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
