Build a ScaleIO distributed storage cluster under CentOS7

ScaleIO is a set of EMC SDS software-defined storage solutions. It uses the company's existing servers to create a shared block storage architecture, improves the efficiency of enterprise resource utilization, and meets the scalability and capacity requirements of enterprise IT.

ScaleIO has an enterprise-level flexible design that supports future applications, catering to the needs of ultra-large-scale deployment and lower operating costs. By using the scale-out server SAN architecture established by ScaleIO, enterprises can have linear capacity growth from several servers to thousands of servers.

In the ScaleIO product community [EMC Community Network (EMC Community Network, ECN)], users can exchange technical support, ScaleIO product issues, product documentation, download ScaleIO, user guides, and more.

1、 Download ScaleIO CentOS7 related rpm package

http://ftp.ufanet.ru/pub/scaleio/RH/2.5.0.254/RHEL7/

2、 Prepare three CentOS7 machines to build a cluster

IP and hostname are as follows

10.20.90.165 node1
10.20.90.166 node2
10.20.90.167 node3

All three nodes install the components required for jdk1.8 and scaleio deployment environment

yum install -y  libnuma*  libaio java-1.8.0-openjdk.x86_64 openssl

And each node is equipped with a 500G data disk

3、 Configure SSH password-free login

The execution in node1 is as follows

ssh-keygen
vi /etc/hosts
# Add the following three lines
10.20.90.165 node1
10.20.90.166 node2
10.20.90.167 node3

ssh-copy-id root@node2
ssh-copy-id root@node3

4、 Install ScaleIO-gateway

mkdir /data/scaleio/
cd /data/scaleio/export GATEWAY_ADMIN_PASSWORD=123456
rpm -ivh /data/scaleio/EMC-ScaleIO-gateway-2.5-0.254.x86_64.rpm

5、 Wizard-style installation and deployment of ScaleIO cluster

Use the import csv method to add nodes, the csv template data is as follows

Start to install and deploy the cluster
