Arcfra AECP 6.3 Deep Dive Collection: Exploring Major Upgrades in Performance, DR, Availability, and O&M

Arcfra AECP 6.3 introduces a major set of updates across performance, disaster recovery, high availability, and large-scale virtual machine (VM) operations. The release brings tier-1 all-flash performance, full-stack business continuity capabilities such as synchronous replication, improved workload resilience for RDMA, SR-IOV, and vGPU scenarios, and operational enhancements that simplify day-to-day management at scale.

This collection brings together in-depth articles on these important updates so readers can quickly find the most relevant technical explanation, use-case guidance, and implementation context.

Four Features Behind Tier-1 All-Flash Performance

AECP 6.3 reaches more than 11 million IOPS and 130 GiB/s bandwidth by combining four storage-layer improvements: IO_uring reduces I/O path overhead, Intel DSA offloads data movement, multi-link aggregation improves network throughput and resilience, and multi-instance storage scales performance across modern hardware.

Full-Stack Disaster Recovery with Synchronous Replication and Arcfra Operation Center High Availability

AECP 6.3 extends disaster recovery beyond data replication by combining VM-level synchronous replication (RPO=0) with Arcfra Operation Center high availability. By combining existing asynchronous replication and backup capabilities, AECP 6.3 offers an end-to-end disaster recovery solution that covers data protection, business recovery, and platform management, ensuring a full-stack disaster recovery loop.

RDMA Cross-NIC HA for High-Performance Workload Reliability

RDMA delivers low latency and high throughput, but a single NIC failure can still disrupt performance-sensitive workloads if the network path is not protected. AECP 6.3 addresses this with cross-NIC bonding, adding NIC-level resilience for RDMA environments. This meets the redundancy requirements of dual-NIC and dual-switch architectures required by financial services and other mission-critical workloads. Read the article

Expanding VM HA to SR-IOV and vGPU Workloads

SR-IOV and vGPU workloads traditionally trade off availability for direct hardware access and acceleration. AECP 6.3 uses the innovative device tagging to make these workloads recoverable under VM HA policies, becoming the first in the industry to support HA for both VMs using SR-IOV and vGPU devices.

Four Key Features to Simplify Large-scale VM Operations

AECP 6.3 reduces repetitive operational work across large VM environments with batch VMTools upgrades, SSH port modification, NTP synchronization, and multi-level VM grouping. Teams can reduce manual steps, enforce consistent configurations, and organize VM estates in a way that maps better to real operational ownership. Read the article
