Notes for using Hyper-V

Brief system interruption during synchronization process
In the synchronization process of CPU modules, a memory copy is performed to duplex memory on both CPU modules. Most of the
memory area can be copied without interrupting the system through the so-called brownout copy method, and just a small portion
requires the system to stop. However, with Hyper-V, the system cannot use the brownout copy method. Therefore, the system does
not respond for a longer period of time during the synchronization process of the CPU modules than without Hyper-V.
See the table below for the reference values of interruption during re-synchronization of CPU/IO modules in a Hyper-V system. It is
recommended that your system design take the interruption into account.

Express5800/R320f-M4
Backup
When using Hyper-V on a FT server, prepare a separate server for backup in the same way as for other general purpose servers
with Hyper-V. For backup patterns, refer to each backup software company's web site.
NEC ESMPRO Agent
For monitoring guest operating systems, NEC ESMPRO Agent for Guest OS is required. Contact your sales representative for this
software.

About Windows Server 2016 License Count on ft Server

License definition
The basic way to understand Windows Server 2016 license definition of ft Server is not different from that of a general server. It
should be noted that licenses on ft Server are counted based on the number of physical cores, but when OS of OEM version is used,
licenses are counted based on the number of cores mounted in one system on ft Server.
Attention is required, on the other hand, in the case with OS (such as PKG version and VL version) other than OEM version, the
above special rule of core counting on one system is not applied.
---
Same as the conventional systems, "Server License" and "Client Access License (CAL)" are required. To use Windows Server 2016
server, CAL of Windows Server 2016 is necessary (old CAL such as that of Windows Server 2012 cannot be applied, therefore, CAL
of Windows Server 2016 should be purchased).
The system of counting server license transitioned from "CPU-based license" to "CPU core-based license". If the configuration is
within 2 CPUs with 16 cores, the rule of counting licenses are the same as before, however, if it exceeds 2 CPUs with 16 cores, the
rule differs from before.
<Three rules>
1. All physical cores in the server are required to be licensed.
2. Each physical processor is required to be licensed with a minimum of 8 physical cores.
3. Each physical server is required to be licensed with a minimum of 16 physical cores.
[Ex.1] 10cores R320f-E4, 1CPU  OEM version: 10 cores mounted on one system,
[Ex.2] 10cores R320f-E4, 2CPUs  OEM version: 20 core licenses are required for the cores mounted on one system.
[Ex.3] 14 cores R320f-M4, 2CPUs  OEM version: 28 core licenses are required for the cores mounted on one system.
