High Availability Meets High Performance

The Intel® Optane™ SSD DC D4800X Offers:

  • 24x7 data availability with redundant paths and hot-plug capability for continued data access in the event of a failure

  • High performance, low latency data placed on Intel® Optane™ SSDs to accelerate data delivery and amplify system performance of capacity NAND SSDs

  • Use as a high speed buffer cache for warm data stored on dense high-capacity Intel® QLC 3D NAND SSDs—providing efficient storage of bulk data with increased performance



High availability and performance are crucial for enterprise storage architectures providing mission-critical applications, such as online transaction processing for financial services. The Intel® Optane™ SSD DC D4800X with its unique combination of dual port PCIe NVMe, consistent low latency, and high random read/write performance, delivers the performance, and capabilities required for enterprise-class storage arrays.

The SSD DC D4800X provides dual port redundancy for maximum data availability during system upgrades or a failover event, enabling enterprise class capabilities and serviceability in high availability storage systems.

Intel® Optane™ SSDs Break Through NAND Bottlenecks
Intel® Optane™ technology provides industry-leading capabilities of breakthrough performance, predictably fast service, responsiveness under load and high endurance. The first Intel® Optane™ technology-based dual port drive can break the NAND bottleneck to help deliver higher service levels to mission-critical applications and reduce transaction costs for latency sensitive workloads.

Combining breakthrough performance with data path redundancy enables enterprise storage array providers to design solutions capable of:

  • Extremely consistent and fast response times even in the presence of increasing write pressure
  • High-performance at low queue depths commonly found in enterprise workloads
  • Predictably fast service—faster than NAND SSDs
  • Supporting write-intensive workloads common in areas such as OLTP and high performance computing (HPC) with high endurance

Key Features
The dual port Intel® Optane™ SSD DC D4800X provides enterprise storage features, including hot pluggable removal and insertion, allowing in-service replacement options. Other key features include:

  • VSS (Variable Sector Size): 512, 520, 4096, 4104 bytes
  • Up to 16 multiple dynamic name spaces
  • 128 queue pair/ port
  • Reservation
  • SGL (scatter gather lists)
  • CMB (control memory buffer)
  • OPAL2.0
  • FIPs140-2

Product and Performance Information


Performance measured using FIO version 3.5 (ioengine=pvsync2 hipri for QD1) OS: CentOS* 7.3.1611 Kernel: 4.14.50. Measurements are performed on a full Logical Block Address (LBA) span of the drive. Power mode set at PM0. Drive formatted with 512byte sector size. Performance collected with aggregation from two hosts accessing two equal sized namespaces from the drive. Average measurement. Results can vary based on setup and measurement window.


Measured using FIO version 3.5 on Linux OS: CentOS* 7.3.1611 Kernel: 4.14.50. Quality of Service measured using 4KB transfer size on a random workload on a full LBA span of the drive once the workload has reached steady state but including all background activities required for normal operation and data reliability. Runtime is 20 minutes. Based on Random 4KB QD=1, 32 workloads, measured as the time taken for 99.9 (or 99.99) percentile of commands to finish the round-trip from host to drive and back to host.
