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. Or, you can install the Catalogic vStor server on a generic Linux machine that satisfies the system requirement.
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 is installed on the vStor server and scanned in as a DPX 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 4.5.2 or later. For Agentless backups to vStor, the virtualization proxy server must be running DPX 4.5.2 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 4. Specification of the Catalogic vStor virtual appliance for VMware or Microsoft Hyper-V
System component | Default configuration |
---|---|
CPUs | Four virtual CPUs |
Memory | 16 GB |
Operating system | AlmaLinux 8.7 for Catalogic vStor |
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 5. 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 6. 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. |
Operating system | AlmaLinux 8.7* |
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) |
Note. Although Catalogic Software has tested Catalogic vStor with AlmaLinux 8.5 and 8.7, Red Hat Enterprise Linux and its variants such as Rocky Linux and Oracle Linux Red Hat Compatibility Kernel are very likely to work too. Use Version 8.5 or later minor versions of the 8 series such as 8.7. Do not use Version 9 or later. Do not use Oracle Linux Unbreakable Enterprise Kernel (UEK) or CentOS Stream 8.
