Rechenzentrum NVMe™ leseintensive SSD

KIOXIA CD7-R E3.S Formfaktor-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. Die CD7-R E3.S Formfaktor-Serie SSDs wurden mit einer PCIe® 5.0 (32 GT/s x4)-Schnittstellentechnologie entwickelt und bieten eine konsistente Leistung von bis zu 1.050.000 IOPS (Random Read) und 180K IOPS (Random Write) bei einem aktiven Stromverbrauch von 13-19 W.

Ausgestattet mit dem BiCS FLASH™ 96-Layer-3D-TLC-Speicher der KIOXIA Corporation bieten die CD7–R E3.S Formfaktor-SSDs 1 DWPD (Drive Writes Per Day) bei einer Speicherkapazität von bis zu 7,68TB in einem E3.S-Formfaktor. 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).
  • [1] Sanitize Instant Erase (SIE) security optional model is 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] Security optional model is not available in all countries due to export and local regulations.
  • PCIe is a registered trademark of PCI-SIG.
  • NVMe is a registered or unregistered mark of NVM Express, Inc. in the United States and other countries.
  • Other company names, product names, and service names may be trademarks of third-party companies.
