Q8D31A Use Case
High-Availability Data Center Maintenance
In a global enterprise data center, IT operations schedule proactive maintenance on HPE CS220G-X4 nodes. By staging the Q8D31A-NS CS220G-X4 Controller/PS/HDD/SSD Spare Kit on-site, technicians can hot-swap failed controllers, power supplies and storage modules in under five minutes. This approach preserves RAID redundancy, meets 99.99% uptime SLAs and drives down mean time to repair (MTTR) for mission-critical workloads.
Rapid Disaster Recovery for Financial Trading
A high-frequency trading firm experiences a controller failure on its primary CS220G-X4 server during peak market hours. Leveraging an on-premises Q8D31A-NS spare kit, engineers perform an immediate controller and SSD module replacement with zero configuration drift. The result is sub-10-minute service restoration, uninterrupted transaction processing and full regulatory compliance under stringent recovery time objectives (RTOs).
Scalable Virtualization Deployment for Enterprise IT
An enterprise IT department rolls out a new VMware cluster across multiple CS220G-X4 nodes to support remote workforce demands. By pre-staging Q8D31A-NS spare kits—including controllers, power supplies, HDDs and SSDs—teams reduce provisioning time and streamline rack-and-stack operations. This strategy accelerates VM deployment by 40%, optimizes capacity planning and ensures high-performance storage at scale.
