Disque SSD pour centre de données NVMe™

Les disques SSD E1.S de la série KIOXIA XD7P ont été conçus au format EDSFF (Enterprise and Datacenter Standard Form Factor) E1.S pour répondre aux exigences spécifiques des applications hyperscale, notamment les exigences de performances, de puissance et de chaleur de la spécification Open Compute Project (OCP) Datacenter NVMe™ SSD. En plus de l’épaisseur E1.S de 9,5 mm, l’épaisseur E1.S de 15 mm avec le dissipateur thermique est également prise en charge. Conçus pour améliorer la densité et l’efficacité du système, les disques SSD série XD7P représentent le futur du stockage flash pour les serveurs et les systèmes de stockage installés dans des centres de données cloud et hyperscale allant jusqu'à 7,68 To.

  • Definition of capacity: KIOXIA Corporation defines a megabyte (MB) as 1,000,000 bytes, a gigabyte (GB) as 1,000,000,000 bytes and a terabyte (TB) as 1,000,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1 GB = 2^30 = 1,073,741,824 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, and/or pre-installed software applications, or media content. Actual formatted capacity may vary.
  • GT/s: Giga Transfers per second.
  • A kibibyte (KiB) means 2^10, or 1,024 bytes.
  • MTTF (Mean Time to Failure) is not a guarantee or estimate of product life; it is a statistical value related to mean failure rates for a large number of products which may not accurately reflect actual operation. Actual operating life of the product may be different from the MTTF.
  • DWPD: Drive Writes Per Day. One full drive write per day means the drive can be written and re-written to full capacity once a day every day for the specified lifetime. Actual results may vary due to system configuration, usage and other factors.
  • Read and write speed may vary depending on various factors such as host devices, software (drivers, OS etc.), and read/write conditions.
  • IOPS: Input Output Per Second (or the number of I/O operations per second).
  • Temperature (operating): Specified by the composite temperature reported by SMART.
  • SED optional model supports TCG Opal SSC except for some features. For more details, please make inquiries through “Contact us”.
  • SED optional model is not available in all countries due to the local regulations.
