I agree. One of the things you can do with mini-split units is create a reasonable degree of redundancy for not very much money. In some places in the world it's very, very difficult to find an air conditioner technician who really knows how to work on large (48,000btu/H and larger) units properly. And such units are hard to source from vendors.
But you can buy 18k and 24k BTU/h mini split units cheap. For larger server/telecom environments you can install them in a load sharing arrangement such as four 24k BTU/h units all running at the same time to cool the same space. You can bring down one unit at a time for cleaning and maintenance or repair without worrying about heat buildup, if you've done your calculations right. The total cost can be under $5000-6000 for the whole setup. Sort of like a RAID array of individual air conditioners. Or a small httpd cluster of 3 or 4 Linux boxes all serving the same content.
