Hello,  Joe is correct, it's very important that you operate within the support limits of the array.  To make this easier, I suggest you upgrade to EQL FW 6.0.4, and upgrade any HIT or MEM products to the latest.  6.x firmware and current EQL MPIO products now work together to better manage connections.  Especially when you are over the limit.  This coordination reduces the connection count automatically.   i'm wondering if you are using VMware ESX?   We see that quiite often with ESX.  There are a number of strategies to reduce the count without losing performance.    Feel free to open a support case with Dell.   We can review your environment and make specific recommendations to correct this issue.   It is very important that you do address this.   Regards, 
We have an EqualLogic iSCSI SAN that has exceeded the limits for iSCSI connections. The limit is 1024 but we are at 1612. The thing is that nothing appears to be affected. We can still add LUNs/servers etc. Are we likely to hit problems? Some sort of performance issue? There doesn't appear to be much documentation on this anywhere! We are firmware 5.2.2. I know what we can do to reduce the connection count, what I want to know is what happens if we don't? Because as far as I can tell nothing bad has happened. Do we ignore it? Panic? 
EqualLogic iSCSI connection limit exceeded - implications?
