Global-active device cloud quorum running on SUSE 15 SP6 monitors data consistency between storage arrays in a Hitachi Global-active device configuration.

Overview
Global-active device (GAD) enables you to create and maintain synchronous, remote copies of data volumes. A quorum disk is used to monitor the GAD pair volumes. The quorum disk acts as a heartbeat for the GAD pair, with both storage systems accessing the quorum disk to check on each other. Global-active device cloud quorum brings the quorum disk to the cloud, removing the need for an on-premise quorum and simplifying configuration for GAD users.
Highlights
- Deploy a GAD quorum in minutes using our Global-Active Device Cloud Quorum Image with pre-configured scripts to automate the process
- View and makes changes to your quorum using the Global-Active Device Cloud Quorum menu user-interface

Dimensions summary
This listing is offered at no software charge. It has one pricing dimension, billed hourly on a t3.medium EC2 instance. Because the software is free, your only cost is the underlying AWS infrastructure for running that instance. The cloud quorum acts as a witness that supports resilient replication setups across cloud environments. There are no tiers or size options to choose between here — you deploy the single instance type and pay standard AWS compute rates for the time it runs.
Top-of-mind questions for buyers
The software itself carries no charge. The hourly rate reflects the underlying AWS EC2 compute for a t3.medium instance. You pay standard AWS rates for each hour the instance runs. There is one instance type only, so no compute sizing choices affect the bill.
There is no software charge at any time. Charges track the running EC2 instance-hours. A fully stopped instance stops accruing compute charges, though attached AWS storage may still incur AWS fees. The software license adds nothing regardless of running state.
The quorum acts as a witness supporting resilient replication across cloud environments. It helps coordinate bi-directional replication so applications stay available if one site fails. It runs on a single t3.medium instance and requires no size selection.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
Version release notes
Global-Active Device Cloud Quorum for AWS: Release Notes v2.2.3
This release improves setup reliability, adds easier quorum scaling, introduces an iSCSI monitoring utility, and updates the base operating system to SUSE Linux Enterprise Server 15 SP7 with the latest security patches.
What's New
This version supports dynamic quorum count adjustment by resizing the attached EBS data volume. This allows customers to increase supported quorum capacity without redeploying the instance.
A new iscsi_monitor.sh utility is included to help monitor the local iSCSI target. The utility can be started, stopped, restarted, or checked for status, and it records iSCSI session, connection, kernel, journal, mapped-LUN, and targetcli activity logs under /var/log/iscsi_monitor/.
Improvements and Fixes
The initial setup process has been hardened to prevent incorrect data-disk selection on AWS instances with multiple block devices or changing NVMe device names. The setup script now identifies the root disk, excludes mounted or active disks, verifies the correct unused data disk, and stops with a clear error if the expected disk cannot be safely determined.
The setup workflow also includes stronger failure detection for disk partitioning, LVM creation, filesystem creation, mounting, and targetcli configuration steps. This makes setup failures easier to diagnose and prevents silent or partial configuration.
Security Updates
The base image has been upgraded to SUSE Linux Enterprise Server 15 SP7 with the latest available security patches. When iscsi_monitor.sh is enabled, administrative targetcli commands are also captured through the Linux audit subsystem for improved operational tracking.
Summary
Version v2.2.3 adds EBS-based quorum scaling, includes a new iSCSI monitoring tool, improves setup reliability on multi-disk and NVMe-based AWS instances, strengthens setup error handling, and updates the base OS to SLES 15 SP7.
