SANs -- Dell EqualLogic vs Microsoft Storage Spaces ?

I am thinking about dropping our EqualLogic SANs at some point and doing the Ditch the SANs: Storage Spaces Is a Workable, Cheaper Alternative talked about on http://betanews.com/2014/09/29/migrating-from-windows-server-2003-12-best-practices-straight-from-the-trenches since I am an all Microsoft shop.

Do you have any articles showing why EqualLogic SANs are better ?

If you are a Dell shop then:
 + (2) R720 with a pair of Dell 6Gbps SAS HBAs and two x540T4 PCIe 10GbE
 + (1) MD1220 (2U 24 drive) or MD3060e (4U 60 drive) JBOD
 + (2) NETGEAR XS712T 10GbE or alternative 10GbE switching

Depending on your storage needs the above setup will yield an aggregate of 40GbE per switch for the two Scale-Out File Server nodes to your compute (Hyper-V). Your compute would require two X540T2 NICs as well.

The above storage solution utilizes one SAS cable (Four 6Gbps SAS channels per cable) per HBA per node. That's four cables in total connected to the JBOD for an aggregate of 96Gbps of ultra-low latency bandwidth between SOFS and the JBOD.

We have Hyper-Converged solutions that only have two nodes and one JBOD set up. Both SOFS and Hyper-V run in this configuration.

We have two SOFS and two Hyper-V node cluster configurations running a single 60-bay JBOD delivering multi-tenant services (IaaS) to Cloud based clients.

NOTE: We use Quanta or DataON JBOD enclosures depending on our needs. They allow for more nodes and JBODs to be connected simultaneously. The Dells, unfortunately, have a limited number of SAS ports per controller.

Why more SOFS nodes and JBODs? With 3 JBODs set up we can run Storage Spaces in enclosure awareness mode. If one enclosure drops off for any reason SS keeps moving along until the problem is repaired.

The Storage Spaces/SOFS solution set is very flexible, scalable, and affordable relative to the big storage vendors out there. Me thinks that Microsoft's Data Centre push is the reason behind it eh? ;)
I'd go ZFS before M$ storage spaces.

Who do you phone when it goes wrong? Microsoft because it's their software or Dill because it's their hardware? How long will it be down because ms and dill bounce the fault between them compared to a single vendor (hardware+firmware) solution?
