It's certainly far better than anything else we'd looked at (EMC somethings & HP EVAs at the time). For me, 3PAR had the edge over Compellent, purely based on an ease of use and attitude of their sales/tech guys (they were very down to earth and honest about their produce. They claim this is their culture as they were founded by ex-Sun engineers).
3PAR and Compellent both do thin provisioning (give your servers 100Gb space even though you only have 50G real - add more disks as needed rather than repartition) and variable performance for specific disk areas (start your data out on SATA, use a specific bunch of files lots and it'll progress up to SAS, then up to SSD if it's continually used).
Everything else we saw was the old SAN way of "you want 300Gb RAID6? You need 4x 300G SATA/SAS/Fibre/SSD drives. Want to move it to another disk type later? Buy another 4 drives and move the data yourself". Really kinda crap in comparison!
We've still not bought anything to replace our old HP silos, but that's due to other projects. It'll certainly be one of HPAR or Compellents offerings - I'm guessing we'll lean HPAR, as we buy lots of HP kit already. I just hope HP don't ruin what appears to be an awesome thing!
