hyperconverged infrastructure performance for the most latency-sensitive workloads. Each node is configured with the
following (for details, see Table 1):
¡´ Hard-disk drives (HDDs), solid-state disk (SSD), or NVMe drives for capacity-layer storage (self-encrypting drive
options are available)
¡´ Write-logging SAS SSD or NVMe drive (self-encrypting drive options are available)
¡´ Data platform logging drive
¡´ M.2 SATA drives as boot drives for VMware vSphere
¡´ One Cisco UCS virtual interface card (VIC)
¡´ VMware vSphere ESXi 6.0 software preinstalled (ESXi 6.5 is supported but is not preinstalled)
¡´ Cisco UCS service profile templates for automated cluster configuration
All nodes use Intel Xeon Scalable CPUs and next-generation DDR4 memory and offer 12-Gbps SAS throughput. They
deliver significant performance and efficiency gains and outstanding levels of adaptability in a 1-rack-unit (1RU) form factor.
Figure 1. Cisco HyperFlex cluster node and management options
Powering next-generation applications
The HX220c M5 Node, HX220c M5 All Flash Node, and HX220c M5 All NVMe Node with Intel Xeon Scalable CPUs are
excellent for a wide range of enterprise workloads, including cloud computing, virtual desktop infrastructure (VDI),
databases including SQL, Oracle, and SAP, and server virtualization.
For remote-office and branch-office (ROBO) locations, you can use Cisco HyperFlex Edge, which is based on the HX220c
M5 Node, in the following configurations:
¡´ Three nodes connected directly to 1-Gbps switches
¡´ Option for one CPU per node
¡´ Three or more disk drives in each node

Capability to use 16-, 32-, 64-, or 128-GB DIMMs
1 or 2 Intel Xeon
Scalable processors
Built on 14-nanometer (nm) processor technology, Intel Xeon Scalable processors are designed to deliver highly
robust capabilities with outstanding performance, security, and agility.
! Up to 28 cores in 2-socket configurations
! Top-of-the-line memory-channel performance
! Three Intel Ultra Path Interconnect (UPI) links across sockets for improved scalability and interconnect data flow
! Hardware-assisted security advancements
! Low-power, high-speed DDR4 memory technology
! Increased performance with Intel Automated Vector Extensions 2 (AVX2)
! Increased virtual machine density
! Automated energy efficiency that reduces energy costs by automatically putting the processor and memory in the
lowest available power state while still delivering the performance required
! Flexible virtualization technology that optimizes performance for virtualized environments, including processor
support for migration and direct I/O
! Innovation with the latest processors, which increase processor frequency and improve security
With the increased performance provided by the Intel Xeon Scalable processors, Cisco HyperFlex HX-Series nodes
offer an improved price-to-performance ratio, making HX-Series systems among the best values in the industry.
