Configuration Requirement
l The arbitration software can be deployed on either a physical
machine or a virtual machine (VM). The configuration
requirements are as follows:
– CPU: X86-64 architecture; 2-core 1.6 GHz CPU (minimum
configuration)
– Memory: 4 GB DDR memory (minimum configuration)
– Operating system: Asianux Server 4 SP4 for x86_64, CentOS
6.5 for x86_64, NeoKylin 6.5 for x86_64, Red Hat Enterprise
Linux 6 for x86_64, Red Hat Enterprise Linux 6.1 for
x86_64, Red Hat Enterprise Linux 6.2 for x86_64, Red Hat
Enterprise Linux 6.3 for x86_64, Red Hat Enterprise Linux
6.5 for x86_64, Red Hat Enterprise Linux 6.6 for x86_64,
Red Hat Enterprise Linux 6.7 for x86_64, Red Hat Enterprise
Linux 7.2 for x86_64, Red Hat Enterprise Linux 7.2 for
x86_64, SUSE Linux Enterprise Server 11 SP1 for x86_64,
SUSE Linux Enterprise Server 11 SP2 for x86_64, SUSE
Linux Enterprise Server 11 SP3 for x86_64, SUSE Linux
Enterprise Server 11 SP4 for x86_64, SUSE Linux Enterprise
Server 12 SP2 for x86_64, Ubuntu 14.04 LTS for x86_64,
CentOS 6.8 for x86_64
NOTE
V300R006C00SPC100 and later versions support CentOS 6.8.
The arbitration software does not support operating systems that use
CPU architectures such as MIPS, ARM, and PPC.
– Storage capacity for installing the arbitration software: ≥ 10
GB
– Number of network ports: ≥ 3
NOTE
One network port is used for operating system management and the
other two are used as arbitration ports that connect to the storage
arrays.
l In the event of virtual machine deployment, virtual machines can
only use servers' local disks or LUNs that are provided by other
storage systems instead of the active-active storage systems as
system disks and data disks.
l Arbitration granularity can be a HyperMetro pair or a consistency
group.
l The versions of the local and remote storage systems in a
HyperMetro relationship are the same. In addition, the hardware
configurations of the two storage systems are the same.
l The HyperMetro license must be available for the storage arrays
in two data centers.
