Catalogic vStor Server Requirements

For a quick, safe, complete, and versatile data protection and recovery strategy, Catalogic has developed the vStor server. The vStor server, connected to disk storage pools, is a reliable streamlined tool that can serve as your DPX primary backup destination.

• You can deploy the Catalogic vStor virtual appliances in VMware or Microsoft Hyper-V environments.
• For backups to and recoveries from a vStor server, both Block backups and Agentless backups are supported. File, NDMP, or archive backups are supported if DPX Client is installed on the vStor server (default configuration starting from vStor 4.10) and added as a DPX Client node.
• BMR recovery is supported for Windows and Linux Block backup to vStor servers. Linux client node requires kernel 3.10 or later.
• For Block backups to vStor, the Backup client must be running DPX 4.9.2 or later. For Agentless backups to vStor, the virtualization proxy server must be running DPX 4.9.2 or later.
• vStor is supported as a DPX Archive source for Block and Agentless backups.

Before you deploy the Catalogic vStor virtual appliance for VMware or Microsoft Hyper-V, review the following specification of it:

Table 2. Specification of the Catalogic vStor virtual appliance for VMware or Microsoft Hyper-V

System component	Default configuration
CPUs	Four virtual CPUs
Memory	16 GB
Hard disks	System disk (50 GB) and Starter disk (100 GB)

Ensure that the system resources for the virtual machines are exclusively reserved in the hypervisor so that it does not share or reallocate with other virtual machines. Also, review the following table that summarizes the recommended configurations of the disks and network adapters:

Table 3. Recommended configuration of the Catalogic vStor virtual appliance

System component	Recommended configuration
Data disk subsystem	Direct-attached storage (DAS); Physical raw device mappings (physical RDMs or pRDMs); at least 120 MB/s of bandwidth
Log disks	Two 10-GB disks with LUNs
Cache disk	100 GB
Network adapter	10 Gigabit Ethernet (10 GbE)

Alternatively, you can install the Catalogic vStor for Linux on a generic machine that meets the following system requirements:

Table 4. Required configurations for the Catalogic vStor for Linux

System component	Required configuration
CPUs	At least 4 CPUs or 4 CPU cores
Memory	At least 32 GB without deduplication; or At least 64 GB with deduplication.
Data disk subsystem	Direct-attached storage (DAS); At least 120 MB/s of bandwidth; RAID 5 with hot-spare disks
Network adapter	10 Gigabit Ethernet (10 GbE)
