  1. Use Putty to log in to the server where the eReplication Server is installed.
    • Template-based installation mode: Log in as user DRManager, and run the su rootcommand to switch to user root.
    • Software package-based installation mode: Log in as userroot.
    NOTE:
    The default password of user DRManager is Huawei@CLOUD8. For the template-based installation mode, the default password of user root is Huawei@CLOUD8!.
  2. Run the Runtime/LegoRuntime/conf/lego.properties command. The following information is displayed:
    system.user.limit.totals=
    system.user.limit.online=
    NOTE:

    Restriction on the number of system users: system.user.limit.totals.

    Restriction on the number of system sessions: system.user.limit.online.

Total number of user sessions

Deployment Environment Specifications

eReplication contains eReplication Server and eReplication Agent. Table 1-3 and Table 1-6 describe their respective deployment environment requirements.

Table 1-3  eReplication Server environment specifications

Specifications

Requirement

Operating system

  • SUSE Linux Enterprise Server 11 SP1/SP2/SP3 x86_64
  • SUSE Linux Enterprise Server 12 SP2 x86_64
  • RedHat Linux 6.4 x86_64
  • RedHat Linux 7.2/7.3 x84_64
  • Microsoft Windows Server 2008 R2 Standard/Enterprise/Datacenter x86_64
  • Microsoft Windows Server 2012/2012 R2 Standard x86_64
  • Microsoft Windows Server 2016 x86_64
NOTICE:
For RedHat Linux 7.2/7.3 x84_64, when a user installs the operating system, Base Environment in SOFTWARE SELECTION does not support the default Minimal Install option. You are advised to select Server with GUI.

CPU

  • Minimum configuration: 2-core 1.6 GHz CPU
  • Standard configuration: 4-core 1.6 GHz CPU

Memory

  • Minimum configuration: 4 GB DDR
  • Standard configuration: 8 GB DDR
NOTE:
  • If the physical memory capacity is 4 GB, the available physical memory capacity must be 2 GB at least. If the physical memory capacity is 8 GB, the available physical memory capacity must be 4 GB at least.
  • If the installation environment is a VM, the VM cannot use dynamic memory allocation.
  • If the installation environment is a Linux operating system, the requirements on swap are as follows:
    • If the memory capacity ranges from 4 GB to 16 GB, the swap value must be the same as the memory capacity.
    • If the memory capacity is greater than 16 GB, the swap value must be 16 GB.

Free disk space

10 GB or higher

The minimum free disk space required by a service host

For a FusionSphere OpenStack private cloud DR scenario, check whether partitions of the eReplication Server operating system meet requirements in Table 1-4 and Table 1-5. If any requirement is not met, perform modification as required.
NOTE:

LVM partitions must be used. If you use raw partitions, software may fail to be installed due to insufficient logical partition space.

Bandwidth of the management network

2 Mbit/s or higher

In the Disaster Recovery Data Center Solutions (Active-Passive Mode and Geo-Redundant Mode), if two eReplication Servers are deployed, the bandwidth of the management network between the eReplication Servers is 2 Mbit/s or higher.

Deployment mode

  • Centralized deployment:

    Only one eReplication management server can be deployed, and the server must be interconnected to the management network of data centers.

  • Distributed deployment:

    In the Disaster Recovery Data Center Solutions (Active-Passive Mode and Geo-Redundant Mode), at most two eReplication management servers can be deployed and management networks between the servers must be interconnected.
