The change of owners has gone swimmingly, Doud reports. "We've kept on all the chip designs that were with NetOctave, and they're forming the core team for the HIPP III."
In fact, according to Doud, it's NetOctave's chip that was at the heart of Hifn's initial HIPP III announcement late last year -- the 8300 and 8350 chips, which are due to begin shipping this quarter. Hifn had already been planning HIPP III, but the NetOctave deal gave them a way to jump-start that development, Doud says.
The HIPP III family are Hifn's first in-line security chips. That is, they're intended to sit right behind the physical-layer (PHY) chip, so that every packet must hit the device, making it imperative that the chip do its job without slowing down traffic flow. That's in contrast to a look-aside model, where the security chip sits off of the main flow of traffic, with only selected packets being sent its way.
So what's the difference between the 4300/4350 and the 8300/8350? For one, the 43x0 chips are outfitted to handle the iSCSI protocol. They are also slimmed down, as the 8300/8350 were too expensive for the storage market and carried more traffic than necessary.
"The number of tunnels that you tend to set up in storage is much smaller than the number you have in VPN [virtual private network] environments," Doud says. The 4300 and 4350 chips support only 8,000 tunnels, "whereas for VPNs, some guys doing wireless need hundreds of thousands of tunnels."
To realize the benefits of cloud-native software, an application must actually be cloud-native—designed to run in the cloud, interacting with disaggregated cloud services, fully manageable as code—to deliver the expected benefits.
