Form Factor

Unlike traditional 2.5-inch form factors, the E1.L "ruler" design (322mm x 18mm x 7.5mm) enables unprecedented storage density in server configurations. This innovative form factor allows data centers to maximize storage capacity per rack unit while maintaining optimal thermal performance and airflow characteristics.

Physical Dimensions and Specifications

The KXDZDRJK7T68 measures 322mm in length with a slim 18mm width and 7.5mm height profile. This elongated design facilitates efficient front-loading into specially designed servers and storage enclosures, enabling serviceability without disrupting adjacent components.

Thermal Management Benefits

The E1.L form factor provides superior surface area-to-volume ratio compared to traditional SSDs, allowing for more effective heat dissipation. This thermal efficiency is critical for maintaining consistent performance during sustained workloads in densely packed server environments.

NVMe 1.4 Interface and PCIe 4.0

Leveraging the NVMe 1.4 specification over PCIe 4.0 interface, the XD7P delivers exceptional bandwidth with x4 lane configuration supporting up to 64,000 MB/s theoretical transfer rates. This interface ensures minimal latency and maximum throughput for the most demanding enterprise workloads.

Enterprise-Grade Reliability and Endurance

Designed for 24/7 operation in demanding data center environments, the Kioxia XD7P incorporates multiple layers of protection and endurance enhancement technologies to ensure data integrity and extended service life.

NAND Technology and Wear Leveling

Utilizing Kioxia's BiCS FLASH 3D TLC NAND with advanced wear-leveling algorithms, the XD7P distributes write operations evenly across all memory blocks, preventing premature wear on specific sectors and extending the overall lifespan of the drive.

Applications and Workload

The Kioxia XD7P is engineered for specific enterprise workloads where its combination of capacity, performance, and form factor provides distinct advantages over traditional storage solutions.

Data and Warehouse Storage

The high capacity and sequential performance characteristics make the XD7P ideal for big data applications where large datasets require rapid ingestion and processing. Analytics platforms benefit from the drive's ability to quickly serve data to computational frameworks.

Available Capacities

While this document focuses on the 7.68TB model, KXDZDRJK7T68 the XD7P series is available in multiple capacities including 3.84TB, 7.68TB, 15.36TB, and 30.72TB options, allowing organizations to select the optimal capacity for their specific workload requirements and budget constraints.

Interface and Protocol Details

PCI Express Generation 4

The XD7P utilizes a PCIe 4.0 x4 host interface, compatible with both PCIe 4.0 and PCIe 3.0 host systems (with appropriate performance scaling). The interface supports NVMe 1.4 features including persistent memory region, virtualization enhancements, and improved power management.

NVMe 1.4 Feature Set

Key NVMe 1.4 features implemented include Replay Protected Memory Block (RPMB) for secure storage of authentication data, Sanitize commands for cryptographic erase, and enhanced telemetry capabilities for detailed performance monitoring and health reporting.

Firmware

Comprehensive management features include S.M.A.R.T. attributes for health monitoring, temperature logging, and predictive failure analysis. KXDZDRJK7T68 the drive supports standard NVMe Management Interface for integration with existing data center management frameworks.

Compatibility

The E1.L form factor requires compatible server chassis or adapter cards designed to accommodate the 322mm length. Many modern hyperscale servers include native E1.L support, while traditional servers may require adapter trays or specialized backplanes.

Cabling and Connectivity

The XD7P interfaces directly with the motherboard or through specialized cabling systems in rack-scale designs. Proper cable management and signal integrity considerations are essential for maintaining reliable PCIe 4.0 signaling at high data rates.

Comparative Analysis in Enterprise Storage

Understanding the XD7P's position relative to other enterprise storage solutions helps in making informed technology selection decisions.

Density and Thermal Advantages

Compared to 2.5-inch U.2 NVMe drives, the E1.L form factor provides approximately 2-3x higher storage density in the same rack space while offering superior thermal characteristics due to the elongated design and increased surface area for heat dissipation.
