In a mid-sized enterprise data center running VMware ESXi, IT teams deploy the 774876-B21 HPE DL180 Gen9 24SFF Expander FIO Kit to expand a standard 8-bay chassis to 24 small-form-factor drive bays. This high-density configuration supports up to 24 SSDs or HDDs, enabling consolidation of virtual machines and block storage volumes on a single server. Benefit: Maximized VM density, lower rack-space footprint and reduced total cost of ownership (TCO) with minimal configuration downtime.
A research organization running Spark and Hadoop clusters on HPE DL180 Gen9 leverages the 774876-B21 FIO Kit to increase local disk capacity to 24 SFF drives. By harnessing parallel I/O across NVMe or SAS SSDs, the cluster gains ultra-low latency scratch storage for in-memory analytics and real-time data ingestion. Benefit: Up to 3× faster query performance, linear scale-out for analytics nodes and enhanced throughput for large-scale data processing.
A global services provider builds a backup appliance on HPE DL180 Gen9, integrating the 774876-B21 24SFF Expander FIO Kit to house multi-TB deduplicated backup datasets. Coupled with Veeam and HPE StoreOnce, the expanded drive count delivers high-capacity, fault-tolerant storage for nightly snapshots and rapid RTO. Benefit: Streamlined disaster recovery, 40% reduction in backup window and improved storage utilization with scalable drive expansion.
