Seagate Corvault Configuration
Seagate Corvault Setup with QuantaStor
This guide describes how to integrate a Seagate Corvault system with QuantaStor in a high-availability (HA) configuration using SAS connectivity.
The Corvault system presents logical volumes to QuantaStor which are then used just like any other JBOD connected HDD except that the virtual devices (LUNs) from the Corvault are typically larger such as 60TB, 80TB or 100TB in size.
Supported Connectivity
Seagate Corvault units are always connected to QuantaStor using SAS ports and cabling. You can use one or two connections per Corvault to each QuantaStor server. If you do two connections you must have at least two SAS HBAs in the QuantaStor with SAS HBA1 connecting to IO Module 1 in the Corvault and SAS HBA2 connecting to IO Module 2 in the Corvault.
Architecture Overview
Corvault operates as a dual-controller active/active array that internally uses Seagate's ADAPT erasure coding to provide fault-tolerance and durability in the event of one or more device failures.
Corvault Configuration
QuantaStor has integrated support for configuration and monitoring of the Corvault units. To enable this first navigate to the Controllers & Enclosures section of the WUI then click the button to Add External System.
Controller Network Setup
Volume Creation
- Create disk pools on the Corvault system as required.
- Create volumes (LUNs) from those pools.
- Use large LUN sizes where possible to reduce management overhead.
Host Mapping
- Create host objects for each QuantaStor node.
- Map all volumes to both QuantaStor nodes.
- Enable ALUA / multi-path access.
QuantaStor Configuration
SAN Connectivity
Ensure SAN connectivity is operational:
- For iSCSI:
- Configure static IPs on SAN NICs.
- Configure dedicated VLANs or networks for storage.
- For Fibre Channel:
- Verify zoning is complete.
Disk Discovery
In QuantaStor:
- Navigate to Storage System → Physical Disks.
- Click Rescan Disks.
- Verify Corvault LUNs appear as new block devices.
- Corvault LUNs will appear as external SAN disks, not JBOD devices.
Multipath Verification
Verify that each Corvault LUN has multiple paths:
```bash multipath -ll
