Isilon Blocking Blocks?

According to an U.S. source, Isilon Systems is "heavily back-peddling on their commitment to support iSCSI and block storage."

Last year, the NAS company integrated the iSCSI protocol into its OneFS
operating system, delivering an unified scale-out storage platform for
the enterprise to consolidate file- and block-based applications onto a
single, shared pool of storage.

The reason behind that: EMC, who later bought Isilon, wants to protect its own block-based products.
