What’s New

Sangfor aCloud (previously known as Sangfor HCI) 5.8.6 is the latest and greatest upgrade in its history. In this version, we are introducing Sangfor self-developed cloud management platform aCMP to transform the HCI to a true private cloud platform, based on the industry-leading HCI architecture, customer is able to build a private cloud easily and efficiently. aCMP brings tons of cloud features including multi-tenancy, multi-cluster management, billing, self-service portal and workflow orchestration to enable large scale deployment and lightning time to market, elevating customer’s focus to business innovation. Disaster recovery is another area where aCloud 5.8.6 excels. We are bringing the most powerful disaster recovery capabilities to aCloud 5.8.6 with 1-click failover, seconds-level RPO, disaster recovery drill, incremental failback and visualized DR monitoring, DR is made simple yet comprehensive on aCloud 5.8.6. In addition to aCMP and DR enhancements, aSAN storage performance is being taken to the next level with data striping technology on 5.8.6, we are seeing an average 50% performance increase over previous storage architecture. A great deal of innovation has been injected to aCloud 5.8.6 to make it more reliable, more automated, faster and more advanced, we can’t wait for you to explore more on this new release.

Sangfor aCloud 5.8.6 introduces the following new features and enhancements:


Multi-tenancy. With aCMP multi-tenancy, customers can create multiple tenants with isolated resource pools respectively. Only assigned resource can be accessed managed by tenants to avoid business interference and data leakage. 3 roles can be assigned in the multi-tenancy model, platform admin (in charge of resource distribution, operations, application approval, charge policy, etc.), tenant admin (Responsible for resource application and usage, business topology construction and update, security strategies and resource operations within the organization), user (consuming cloud resources within the tenant).

Multi-cluster management. aCMP provides a centralized management for aCloud clusters across different regions. As long as aCMP is able to communicate with the management port of the aCloud cluster, it is able to manage the cluster.

Self-service portal. User is able to apply for cloud host resource from a self-service portal, tenant admin can access his/her own self-service portal to approve the application from users and he/she is also able to apply for more cloud resources from platform admin. After applications are approved, requested resources will be assigned automatically without any human intervention..

Workflow customization. Admins can customize the resource application approval workflow to accommodate specific organizational structures.

Billing and metering. Admins can charge tenants and users based on how much resources are consumed by them. The billing and metering metrics can be customized based on CPU core, memory and storage capacity. Billing report can be exported for audit.

Image management. aCMP offers a unified management for image files across aCloud clusters. Tenant admin can customize private images within an organization, users can use public images provided by platform admin as well as private images uploaded by tenant admin. Image formats support ISO and acloud (which is used for template VM deployment).

Distributed firewall for multi-tenancy. Tenant can customize its own DFW policy, and it doesn’t conflict with the policy configured by platform admin. A tenant is related to a valid domain, configured ACL policy only applies to switches within this domain.

Support VMware VDC. aCMP supports VMware VDC for lifecycle management of VMware VMs, all the cloud features such as multi-tenancy, workflow and billing apply to VMware clusters.

Unified Licensing. All licenses will be consolidated to aCMP and licensing aCMP will cover and apply to all aCloud hosts.

OpenStack API. aCMP provides industry-standard OpenStack API to enhance ecosystem capability, 3rd party cloud management is able to directly manage aCMP through the API without any code change.

Large scale deployment. Up to 1920 VMs in a single cluster, Unlimited scalability (theoretically, there’s no limitation of how many clusters can be managed by aCMP. R&D tested 40 clusters with 32 aCloud and 8 vCenter), up to 20000 VMs can be deployed and managed by aCMP, support concurrent access by up to 300 users.

Disaster Recovery

1-click failover. 1-click failover can be achieved after preconfiguring disaster recovery policy at the beginning to reduce RTO significantly. With instant recovery, failover time can be as short as 2-5 minutes.

Flexible RPO choices. Providing a wide range of RPO choices ranging from as minimum as 1 second to minutes and hours to meet various application requirements.

Compression and encryption. Data is compressed in LZ4 algorithm with up to 50% compression ratio before transmission to reduce bandwidth consumption. Encryption is also implemented in AES 256 to secure data on the fly.

Incremental failback. Failback is done in an incremental way, only incremental data is transmitted back to production site to realize fast failback.

Disaster recovery drill. User is able to test DR effectiveness with 1-click DR drill function on aCloud.

Continuous backup on the breakpoint. In the event of link failure, replication can be resumed from the breakpoint, no need to restart the backup all over again.

Visualized DR monitoring. A visualized and intuitive GUI to display various of DR metrics for easy and holistic DR monitoring.

Storage Performance Improvement

Data striping. aSAN is now adopted with data striping technology, data stored in QCOW2 is segmented into blocks (maximum 4GB) and stripes in 128KB size, and then distributed into disks across aCloud hosts, performance and concurrency can be improved dramatically based on this technology.

Upgrade for This Release

Sangfor aCloud 5.8.6 supports upgrade from 5.0, 5.2, 5.3, 5.3R1, 5.8.3 and 5.8.5.
