Sonnet Announces New 4U Enclosure to Rack Mount Two Mac Pros

Mounting and organizing options for heavy duty Mac Pro users continue to grow since the new machine's launch at the end of last year, with Sonnet now announcing a new rack mount enclosure capable of holding two Mac Pros. The new enclosure is an additional option to go along with the enclosure and expansion chassis the company announced last week.

This time, the Sonnet Rack Mac Pro allows users to rack mount one or two Mac Pro machines in a 4U space. The unit includes a front panel power button with USB 3.0 port for each machine, plus a second USB 3.0 port, a Gigabit Ethernet port, and an HDMI connector on the back of the rack for each Mac Pro.

There are no rear Thunderbolt ports because, Sonnet says, there are no panel-mount Thunderbolt connectors available. There is, however, room inside the rack for Thunderbolt cables to be attached, and the company says it is "fairly easy" to directly connect Thunderbolt cables and they can be secured to the Mac Pro so they can not be accidentally unplugged.

The Rack Mac Pro also supports the mounting of Thunderbolt to Fibre Channel adapters like the Promise San Link2.

Pricing is expected to be $599 to rack mount a single Mac Pro, with an add-on to mount a second Mac Pro available for $299. Availability is likely to come in June alongside the previously announced combination enclosure and expansion chassis.

It does not make sense to spend hundreds of dollars on top of an already pricey machine simply to rack-mount it. Apple needs to release new dedicated rack-mountable hardware.
So it makes more sense to spend hundreds of millions if not more, when they didn't quite make out the first two times they tried it, designing, setting up manufacturing, marketing, and everything else that goes with selling and SUPPORTING yet another model? :rolleyes:

NEWS FLASH: The market and people who require this setup don't care what the machine looks like, they care what it performs like.

Kinda kills the point of them looking unique, No ?

Which begs the question did they ever need to look that way. The individual or company that needs the power of the pro don't need it to look like a work of art, they just need it functional.

I do motion/video/fx for large productions and travel with my gear all the time.

There's a great practical utility around the MacPro's form factor. For the first time I can easily pack my rig into a carry-on bag. This is a huge deal for me since I'm often asked to render AfterEffects projects on location just hours before showtime.

I'm in the minority, but for me the new Pro has opened up a ton of options for what I can execute while on the road without the hassle of checking in my gear in a tuff case.

Add to that - this rack mount solution is a good approach. We always use redundant machines on location, in case one goes down during a performance.

They cannot sell "functional" by the hundreds of thousands, or perhaps even the tens of thousands.

A third party has provided a solution that Apple will allow that provides such functionality. Sonnet can be profitable with this with a lower volume of sales.

I'll be surprised if they can move one of these things of the shelf. I see a very small purpose for the single mount option, but I wouldn't think anyone would have two MP's in a rack, and why does it cost this much?
In live show work, we almost always have a "Main" and "Backup" computer. This would be perfect for that. Slips into a rack with the other A/V components and makes the MacPros essentially impossible to steal when we're not on site.

Just because you don't know what pros use MacPros for, doesn't mean a market doesn't exist. For Sonnet to go through the trouble to make this, THEY understand the market.
