How are you going to scale out to petabytes with your current infrastructure? Largely unstructured data such as messages, images, and GPS signals from cell phones, are growing at an exponential rate. The HP ProLiant SL4500 Scalable System is the first server purpose-built for big data, offering breakthrough economics, density and scalability.

The System is available in three combinations of compute and storage density, ranging from one to three nodes, and from 60 to 45 large form factor hard drives to meet your scale-out workload needs at lower cost, in the least amount of space, with the reliability and manageability of HP ProLiant.

What's new

  • Supports Intel E5-2400 v2 Processors
  • Supports 6TB HDDs for increased capacity
  • Supports 32GB DIMMs for increased memory capacity


Designed To Support a Range of Storage Capacity per Node with Scalable Performance and Throughput

With the HP ProLiant SL4500 Scalable System you have a choice of three flexible compute nodes in a 4.3U form factor chassis that allows for shared cooling, power and management.
The one-node configuration with 60 drives is ideal for applications such as object storage requiring a large amount of storage capacity.
For applications such as email and data analytics, you get a more balanced core to spindle ratio with the two node configuration with 25 drives for each node.
With parallel processing applications such as Hadoop that require a balanced core to spindle ratio, consider the three node configuration with 15 drives for each node.

Scale in Capacity and Performance at Lower Cost

The 4.3U form factor chassis of the SL4540 is capable of storing up to 360TB. With nine chassis in a 42U rack, it can achieve unprecedented server storage capacities of up to 3.24PB.
Extreme density requires scalable performance. This is achieved with a balanced architecture and HP Smart Array technology that provides the flexibility to balance cost and performance across different drive types (SAS, SATA and SSD).
The Converged Infrastructure design achieves energy savings with shared cooling and power while reducing complexity with fewer cables.
Two 2.5-inch small form factor (SFF) hard drives in every compute node allow for separate boot/OS drives on a separate controller.

Scale Confidently with Built-In Intelligence and Automation

HP Smart Array technology innovations include Predictive Rebuild to reduce downtime exposure, improved data retention with Flash Backed Write Cache (FBWC) and increased data protection with advanced data mirroring.
Seamless management of the cluster, server and storage, with integrated remote support. Deploy applications across all servers with a single command. Control and manage your power at the rack level.
Serviceability at every level with hot-plug critical components (disk drives, nodes, fans and power).
The HP iLO Management Engine offers Agentless Management and Active Health System monitoring. The HP Smart Update Manager enables easy firmware and software updates.
