NVMe™-Rechenzentrum-SSD für hohe Lesevolumen

KIOXIA CD8-R-Serie ist eine auf hohe Lesevolumen ausgelegte Rechenzentren-NVMe™-SSD, die für ein breites Spektrum von Scale-out- und Cloudanwendungen optimiert wurde. Dazu zählen etwa Big Data/IoT, Onlinetransaktionsverarbeitung und Virtualisierung. SSDs der CD8-R-Serie sind mit einer „PCIe® 4.0“-Schnittstelle (16 GT/s x4) ausgestattet und liefern eine konsistente Performance von bis zu 1,250 Millionen IOPS (zufälliges Lesen) bzw. 200.000 IOPS (zufälliges Schreiben).

Ausgestattet mit einem BiCS FLASH™ 112-Layer-3D-TLC-Speicher der KIOXIA Corporation bieten die CD8–R-SSDs (Formfaktor 2,5 Zoll) 1 DWPD (Drive Writes Per Day) bei einer Speicherkapazität von bis zu 15,36 TB in einem Formfaktor von 2,5 Zoll. Damit eignen sich die Speichermedien ideal für den Einsatz in Hyperscale-Rechenzentrumsanwendungen.

  • 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.
