# Hardware

Server

The CIO software runs on bare metal servers, virtual machines, or cloud instances. Three nodes minimum are required for data redundancy. Four nodes are recommended for production clusters.

Bare Metal Server
CPU Duo-Core Intel x86
RAM 64GB
Boot Drive 20GB
Data Drive 3 x 100GB SSDs (recommended)
Ethernet NIC Dual 10GigE (recommended)
Virtual Server/Cloud Instance
CPU 2 or more virtual CPUs
RAM 16GB
Boot Drive 20GB
Data Drive 3 x 100GB SSDs (recommended
Ethernet NIC Dual 1GigE+ (recommended)

While Storidge CIO will operate off one network interface, dual interfaces provides greater network bandwidth and isolation. For applications with heavy I/O workloads, it is highly recommended to dedicate a network interface for internode storage traffic (storage network), and assign a second interface for front end applications.

Important

Four nodes minimum are recommended for production clusters

Data Drive

During installation, CIO will automatically discover and aggregate data drives from each node into a shared storage pool. CIO will only add raw devices to the storage pool, i.e. drives formatted with a file system or partitioned will not be added. Delete the partitions or clear the drive metadata as needed.

Drives with partitions can be cleared using tools such as fdisk. To clear drives that are mounted, first unmount and then clear the metadata area. Example, for device sdb below:

dd if=/dev/zero of=/dev/sdb bs=1M count=300

TIP

The CIO volume management capabilities duplicate and conflict with volume management software such as LVM.

Do not use two volume management software on the same drives.
