Head-fake
Couple of thoughts...
- SimpliVity is no substitute for Nutanix. Cisco's been hooked up w/SimpliVity for some time now and would know it if they were. And, SimpliVity's critical dependency on it's proprietary FPGA implementation is it's Achilles Heel. Somebody at SimpliVity didn't get the memo -- "Software Defined Storage" means no proprietary hardware dependencies.
- Cisco is an early-stage investor in Atlantis and Stratoscale (probably others too). Cisco is doing all of this because they need to exert control over the hyperconvergence trend (meaning, they need to retard adoption). What happens to Cisco's very profitable LAN/SAN convergence strategy when SANs get hyperconverged into the virtualization tier? Goes up in a puff of hyper-smoke, no?
My guess is that this meticulously UN-sourced 'informed speculation' is a Cisco strategy ploy to freeze the market -- essentially it's a head-fake. Strategically, this looks exactly like what Cisco did with iSCSI via NuSpeed in the early 2000s. Cisco never had any intention of letting iSCSI become a data-center convergence standard -- but Cisco bought NuSpeed to freeze data-center adoption of iSCSI and take momentum away from the startups. This gave Cisco time to execute it's real play -- which was Andiamo and FCoE. The difference then was that Cisco could afford to buy NuSpeed ($400mil was pocket change for Chambers then). Today, actually buying Nutanix would cost real money, so in this case a speculative analysts leak is the next best (and less costly) thing.
Cisco will do everything they can to slow or 'contain' hyperconvergence...including buying companies in order to kill them. Like NuSpeed.
