SSD NVMe™ pour centres de données à usage mixte

La série CD8-V de KIOXIA est un disque SSD NVMe™ pour centres de données à usage mixte ayant été optimisée pour prendre en charge une large gamme d’applications évolutives et d’applications cloud incluant les données massives (Big Data/IoT), le traitement transactionnel en ligne et la virtualisation. Conçus avec l’interface PCIe® 4.0 (16 GT/s x4), les disques SSD de la série CD8-V assurent une performance constante allant jusqu’à 1250 K IOPS (lecture aléatoire) et 380 K IOPS (écriture aléatoire).

Disposant d’une mémoire flash 3D TLC BiCS FLASH™ 112 couches de KIOXIA Corporation, les disques SSD de la série CD8-V offrent 3 DWPD (Drive Writes Per Day) d’endurance ainsi qu’une capacité de stockage allant jusqu’à 12,8 To dans un facteur de forme de 2,5 pouces. Ils sont ainsi adaptés aux applications pour centres de données hyperscale.

  • 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.
  • [1] Sanitize Instant Erase (SIE) and Self-Encrypting Drive (SED) security optional models are available.
  • [2] SIE optional model supports Crypto Erase, which is a standardized feature defined by the technical committees (SCSI) of INCITS (the InterNational Committee for Information Technology Standards).
  • [3] SED optional model supports TCG Opal and Ruby SSCs. It has a few unsupported features of TCG Opal SSC. For more details, please make inquiries through “Contact us”.
  • [4] Security optional models are not available in all countries due to export and local regulations.
