Kioxia XD7P Series EDSFF E1.S NVMe SSDs Up to 7.7TB with OCP Data Center NVMe SSD 2.0 Spec Support

Kioxia America, Inc. expanded its portfolio of client, enterprise and data center SSDs with the addition of the XD7P Series.

Designed for hyperscale and general server applications in the Enterprise and Data Center Standard Form Factor (EDSFF) E1.S form factor, XD7P drives are the 2nd generation of E1.S SSDs with Open Compute Project (OCP) Data Center NVMe SSD 2.0 spec support from the company, following its XD6 series. XD7P drives are sampling to select data center customers ⁽¹⁾.

“Hyperscale needs of density, power, performance and serviceability are driving PCIe 5.0, E1.S, as a form factor, and the OCP Data Center NVMe SSD specification V2.0 for the data center,” said Ross Stenfort, hardware storage engineer, Meta. “The Kioxia XD7P Series SSD supports these storage technologies to enable the next generation of hyperscale needs.”

XD7P Series data center NVMe SSDs deliver improved performance, achieving nearly 1.5x to 2x the sequential write performance and random RW performance, when compared to its predecessor ⁽²⁾. These drives are designed to the PCIe 4.0 and NVMe 2.0 specs, and PCIe 5.0 with maximum interface speed of 32GT/s per lane is under development. Hence, XD7P will be released initially as PCIe 4.0 SSDs. PCIe 5.0 SSDs will be released based on customer demand.

EDSFF E1.S form factor

XD7P Series highlights include:

EDSFF E1.S form factor with 9.5, 15 and 25mm heat sink options
Designed to NVMe 2.0 and PCIe 4.0 specs (PCIe 5.0 under development)
Supports the OCP Data Center NVMe SSD 2.0 r21 spec
Built on 5^th generation BiCS FLASH 3D TLC flash memory and an improved proprietary controller
1 DWPD endurance and supports up to 7.68TB capacity
Non-SED and TCG Opal SSC SED options

“As hyperscale data centers get more sophisticated, the E1.S form factor is gaining in popularity over legacy form factors due to its break-through thermal and performance benefits,” said Maulik Sompura, senior director, product planning and management. “Kioxia is pushing the envelope further with our next-gen XD7P E1.S NVMe and PCIe SSDs, which are equipped to support newly added, complex OCP features. With the XD7P, Kioxia has made significant strides in capabilities compared to previous generation drives – which can lead to a substantial TCO advantage for customers.”
