Cisco presented a sneak preview of HyperFlex 4.5 at Storage Field Day 20 a little while ago. You can see videos of the presentation here, and download my rough notes from here. Note that this preview was done some time before the product was officially announced, so there may be a few things that did or didn’t make it into the final product release.
Announcing HyperFlex 4.5
4.5: Meat and Potatoes
So what are the main components of the 4.5 announcement?
- iSCSI Block storage
- N:1 Edge data replication
- New edge platforms / SD-WAN
- HX Application Platform (KVM)
- Intersight K8s Service
- Intersight Workload Optimizer
Other Cool Stuff
- HX Boost Mode – virtual CPU configuration change in HX controller VM, the boost is persistent (scale up).
- ESXi & VC 7.0, Native VC Plugin, 6.0 is EoS, HX Native HTML5 vCenter Plugin (this has been available since HX 4.0)
- Secure Boot – protect the hypervisor against bootloader attacks with secure boot anchored in Cisco hardware root of trust
- Hardened SDS Controller – reduce the attack surface and mitigate against compromised admin credentials
The HX240 Short Depth nodes have been available since HX 4.0, but there’s now a new Edge Option – the HX240 Edge. This is a new 2RU form factor option for HX Edge (2N / 3N / 4N), A-F and hybrid, 1 or 2 sockets, up to 3TB RAM and 175TB capacity, and PCIe slots for dense GPUs.

Thoughts and Further Reading
Some of the drama traditionally associated with HCI marketing seems to have died down now, and people have mostly stopped debating what it is or isn’t, and started focusing on what they can get from the architecture over more traditional infrastructure deployments. Hyperconverged has always had a good story when it comes to compute and storage, but the networking piece has proven problematic in the field. Sure, there have been attempts at making software-defined networking more effective, but some of these efforts have run into trouble when they’ve hit the northbound switches.
When I think of Cisco HyperFlex I think of it as the little HCI solution that could. It doesn’t dominate the industry conversation like some of the other vendors, but it’s certainly had an impact, in much the same way UCS has. I’ve been a big fan of Springpath for some time, and HyperFlex has taken a solid foundation and turned it into something even more versatile and fully featured. I think the key thing to remember with HyperFlex is that it’s a networking company selling this stuff – a networking company that knows what’s up when it comes to connecting all kinds of infrastructure together.
The addition of iSCSI keeps the block storage crowd happy, and the new edge form-factor will have appeal for customers trying to squeeze these boxes into places they probably shouldn’t be going. I’m looking forward to seeing more HyperFlex from Cisco over the next 12 months, as I think it finally has a really good story to tell, particularly when it comes to integration with other Cisco bits and pieces.
