Force10 Thinks 'Exa'

Force10 Networks Inc. is trying to put up some big numbers and claim 100-Gbit/s bragging rights with its ExaScale E-series of switches, being announced today. (See Force10 Intros ExaScale.)

It's the almost-logical sequel to the company's TeraScale switches. (Force10 is apparently opting to skip "peta-," the prefix for 1015 that goes between "tera-" and "exa-.")

The new switch also hints at a future more linked to telecom, through additions like Multiprotocol Label Switching (MPLS). The telecom angle is likely to get more focus once Force10 completes its planned merger with Turin Networks Inc. (See Force10, Turin Play Convergence Card.)

With the data center and virtualization being all the rage, new switches are popping up everywhere. Force10's new entry will get pitted against the Cisco Systems Inc. (Nasdaq: CSCO) Nexus family and the Juniper Networks Inc. (NYSE: JNPR) Stratus "fabric," whatever that is. (See Cisco's Nexus Targets Data Center's Future and Juniper Strikes at the Data Center.)

It's also going to face competition from the Juniper EX 8216 and gear from Arista Networks Inc. , Brocade Communications Systems Inc. (Nasdaq: BRCD), Extreme Networks Inc. (Nasdaq: EXTR), and Woven Systems Inc. (See Juniper Storms Into Ethernet Switching, Ullal Lands in the Cloud, Brocade Takes Aim at Cisco (& Juniper), and Woven Intros Fabric.)

Among ExaScale's claims to fame are 100-Gbit/s slots that Force10 says can really handle 100 Gbit/s, without oversubscription. In other words, it could run ten 10-Gbit/s Ethernet ports per slot simultaneously.

"I don't think anybody can show you they've got this kind of bandwidth per slot," says Steve Garrison, vice president of marketing at Force10.

That means the half-rack ExaScale E1200i, with 14 slots, can pack 140 10-Gbit/s Ethernet ports. That one's shipping today. A smaller version, the ExaScale E600i, will fill one third of a telecom rack and is slated for third-quarter availability.

Arguably, that outdoes the competition, Garrison says. For example, Cisco's Nexus can pack 256 10-Gbit/s Ethernet ports into a half-rack, but only 32 of them can run at line speed, he claims.

That's not to say oversubscription is bad. Eventually, Force10 does intend to produce super-high-density, oversubscribed blades for the ExaScale, Garrison says.

Force10 is trying to work a couple of different angles related to the new data center that's beginning to emerge. It's already been talking up its virtualization capabilities. (See Force10 Gets a View.) And through the merger with Turin, Force10 hopes to increase its switches' roles in linking data centers to the wide area network. Garrison says carriers account for 30 percent of Force10's business.

Force10 has put MPLS into the home-designed ASICs that power the ExaScale, but they won't be activated at first. This kind of MPLS use is likely to come later down the road, because, while telecom customers will embrace it, it's not familar ground for the data center. "Data center managers are going to take a long time to get used to this," Garrison says.

One possible MPLS scenario could arise as carriers offer cloud computing as an enterprise service. That could create a need to use MPLS to give a customer its own Label Switched Path (LSP) between the server edge and the network core.

Garrison says Force10 also expects to add Ethernet-over-Sonet to its gear, considering Turin already uses the technology.

"Looks like this is just another Cabletron, whoops...I mean Yago...errr, no thats ummm...Riverstone, aaag, nope note quite right...empty paper only product announcement."




Cabletron never actually had a massive core Ethernet switch.-á The Yago/Riverstone box that they acquired and then spun out was designed to be much more of a router vs. a switch.-á This product looks to be-ámore of a shot across the bow of Brocade/Foundry... one-upping them along with-áthe products that Cisco and Juniper target at the big data centers.-á Cabletron (now Siemens-Enterasys) targets enterprises almost exclusively.-á

A system that's EXA-ctly the same as before.

Stuart,




I was being SAR-castic so I'll TRA-nslate into ENG-lish.




 




EXA = EXA-ctly the same, meaning Force10 is press releasing nothing in terms of product.-á They are simply re-announcing the fact that their EXISTING backplane architecture and engineering work is capable of accepting 100GbE designed modules sometime in the future.




HOWEVER, the announcement itself is meaningless becuase there's no guarantee that the system will not require upgrades/replacements, etc... nor are they actually shipping/demonstrating those products today.




Bottom line.-á EXA = lipstick on a --- (you fill in the blank with your favorite animal).




Nothing new here folks.-á Just a page out of the Cabletron marketing playbook.

re: Force10 Thinks 'Exa'


I hear what you're saying HF, but I'd have to disagree with you a little bit.-á It seems to me that customers like the bigger carriers or data centers, who value max. uptime, would appreciate having an upgrade path on their deployed chassis/shelves.-áA forklift upgrade to a new chassis is a fairly disruptive process.-á Also, I don't belive 100GE is even standardized yet.

re: Force10 Thinks 'Exa'


SB,




Given the hollow Force10 press release announces nothing but "we're ready for the future when you are" plus your point about 100GE not even being a standard yet, what are the benefits to the customer?-á EXActly nothing.




What's the definition of a forklift upgrade when Force10 is making a paper announcement?-á Can YOU guarantee that Force10 will not force a forklift upgrade with their EXAactly the same chassis given they're not making an EXA-product announcement with product shipping to customers?-á




This is a round-about arguement that brings me right back to my original posting.




This is the EXAct same marketing tactic that Cabletron/Yago/Riverstone used in their non-glorious past - look at how well that served those companies and you can probaly forecast the future of this one.
