EqualLogic 15TB LUN limit
I am kind of stuck between a rock and a hard place. I have a Windows 2012 server with a volume that is almost full at 15TB. The data in the volume is thousands of individual folders with millions of small image files. I was thinking of using either Windows Spanned Volume or a Windows Striped Volume to circumvent the EqualLogic 15TB limit. I know this is not recommended procedure, but can anyone tell me if there are some inherent issues with EqualLogic and using one of these methods or which method is the lesser of the two evils?

Thank you for the response and that's good info about the spanned/striped volume not connecting due to the iSCSI initiator not starting in time. I will have to test that out.
I had considered mounting points but since each folder only contains a relatively very small amount of data and the business will not allow me to alter the structure, ie. archiving, it won't work for me in this instance.

So the way my folder structure is laid out is: D:\Images, then there are just over 2000 subfolders, and within each subfolder there is only about 6 - 7 GB of data.
The software that the business uses requires the data to be placed in D:\Images and then a subfolder. The software then indexes the images for later analysis.
I don't know how the mounting points would work in this situation. Hopefully I am missing something because I would much rather use mounting points rather than spanning or striping.

Maybe another solution.... Windows 2012 supports Deduplication which gives a lot of space back depending on your data. Its enabled per Volume but you can exclude folders and data types as well. There is a testprogam which can "calculate" the space savings. For a typical fileserver we get ratio from 45-60%.
For you next "project" take a look to Microsoft DFS which is there since Server 2003. It gives you a single namespace like \\company.name\share where share is a virtual object which links to a \\share from a file server. A File server can add one or more shares to the DFS tree.
