Introduction to the environment

name	details
The server	JD public cloud ECS：32C/128G/8T( Storage optimization IO Type local NVMe SSD Through plate ) × 5 platform
Operating system version	CentOS Linux release 7.4.1708 (Core)
Operating system kernel version	3.10.0-693.el7.x86_64
ScyllaDB edition	4.4.4

because ScyllaDB The data of the cluster will eventually be SSTable File mode drop disk , Therefore, the performance requirements for disks are very high , In this example, we use the storage optimization provided by JD cloud IO Type local NVMe SSD Through plate .

The old production cluster ScyllaDB The version is 2.3.1, And the clusters are deployed on physical machines , Because of the requirements for disk performance ,ScyllaDB On the official website, it is recommended to adjust the disk array to RAID0, The hard disk array card is used on the physical machine RAID0. This time because it is a virtual machine 、 Through plate （ Bare equipment ）, So soft RAID0 Mode to install and configure , Will eventually generate /var/lib/scylla Data storage directory .
