Low power true converged infrastructure

In the drive to minimize cost, KALEAO has designed KMAX-EP, a hyperconverged integrated software and hardware platform, extremely compact and low power. KMAX-EP provides the full benefits of hyper convergence leveraging advanced software defined hardware and appliance level web-scale application delivery and management.

KMAX-EP solutions are compatible with the vast open source Linux-based software ecosystem available for the ARM platforms, while natively supporting Open Stack along with the additional richness of an industry standard application stores, like Ubuntu JuJu Charms.

True convergence targeted for enterprise IT infrastructure

Enterprise IT teams are under pressure to deliver more capabilities while saving money on operational expenses like space, power, and cooling. KALEAO’s KMAX-EP delivers those benefits, to turn the IT team into heroes.


At just 4U high, KMAX-EP offers compute, storage and networking so IT teams can modernize and consolidate resources while streamlining administration and management processes. There are no longer multiple tiers of separate network resources to manage and coordinate across business units or functions. Instead, system administrators use a single management interface to drive and configure all aspects of the KMAX-EP platform, whether using single chassis or scaled out to multiple cabinets.


Optimized hardware design along with software defined capabilities yields the best of both worlds. Processing speed only possible in hardware, low latency due to short distance between components, and flexibility from software defined operations.


KMAX-EP extends the KALEAO product portfolio specifically for the enterprise environment with a 4U chassis, 48 VDC power or internal AC power supply option, and rear-loading blades to simplify data center operations and workflows.


The KMAX-EP advantage

Up to 4x less energy per workload maximizing resource utilization and reducing your energy bill.
KMAX-EP is the first ARMv8-A server to extend the extreme power efficiency of ARM big-LITTLE technology to the datacenter. The inherent power efficiency of ARM technology required for battery operation, the optimized energy-aware KMAX-EP architecture along with  its unique resource utilization management system and a zero-overhead physicalization make the KMAX-EP unmatched in energy efficient computing.
Over 10x compute density – less space needed to deliver more compute infrastructure.
Building on the inherent low power consumption and advanced power management strategies, KMAX-EP further reduces the operation cost of infrastructure by delivering the highest consolidated server-class compute density available. Packing 1,536 processor cores and 48x slots for up to 370TB of high bandwidth NVMe based flash storage in a single 4U chassis.
Delivers up to 10x as many application operations per chassis.
Software defined hardware through physicalization of the delivery of virtualized resources, minimizing overheads and maintaining the bare metal performance available to the application. Low latency storage and high bandwidth networking arranged in a non-blocking manner are kept independent of the application processor load further maximizing total system performance.
Provision infrastructure on demand
KMAX-EP systems allow growth across compute, storage and network by simply adding resources with a building-block-like efficiency. The additional resources, simply appearing in the global pool of available resources, are managed through the OpenStack based orchestration platform to enable seamless application deployment to a massive scalability.
Leverage  compatibility
KALEAO selects components with market-proven reliability and uses them to build the unique value of the KMAX-EP solution. KMAX-EP preserves full out-of-the-box compatibility with the broad ecosystem of software applications and environments available from the open-source community and ARM-technology based devices.
Eliminates virtualization side-channel flaws
In addition to hardware secured boot, KMAX-EP system architecture offers the setting for full hardware-level independence and non-blocking operation between applications on each server, network and storage resource to increase security and remove contention of the execution environments when needed.
Share anything at hardware level
Through physicalization, KMAX-EP provides a distinctive resource-sharing capability that permits resource aggregation at a physical level. Bare metal pools of networking and storage can be flexibly allocated to specific applications, with enough physical processor cores to remove the need for over-commit on compute
Reduce single points of failure
Due to the high processing core density of KMAX-EP, the ratio between the number of application domains required to share a physical core to realize a return on the hardware investments are significantly lower than those typical in todays x86 based system.  This approach not only limits the impact of any failure, but also ensures each application can receive the full GHz performance potential of the assigned processor.
Administration agility
KALEAO’s appliance system integrates compute, storage, networking resources with a pre-installed and fully integrated software stack for the effortless deployment and management of application services with a plug and play simplicity.  Together with built-in hyperconverged functionality, this enables an increase in the efficiency of IT staff while reducing the need for expertise-silos, minimizing deployment time and increasing overall system manageability.
