Minimum x8 Physical slot is required with minimum electrical connection x8 for optimal performance on PCIe Gen. 3. The card is backward-compatible with PCIe Gen. 2 & Gen. 11. Additionally, it supports x4, x2, and x1 modes in a compatible socket. FAQ: DCP1000-01
Any recent chipset supporting PCIe Gen. 3 is sufficient. For example, i5/i7 chipsets have been tested and validated. Intel E3-1xxx and E5-2xxx chipsets have been tested and validated. The E5s can be v2, v3, or beyond. FAQ: DCP1000-02
The DCP1000 will present itself as 4 physical devices. The system BIOS and OS will see 4 physical independent SSDs. The drive can be configured to a single RAID or be used as 4 independent drives. FAQ: DCP1000-03
No. The DCP1000 is a plug-n-play device that works with most newer operating systems. The mMajority of Linux and Windows OS versions today have in-box NVMe drivers. The DCP1000 is compatible with the preinstalled in-box Linux and Windows NVMe drivers. FAQ: DCP1000-04
The DCP1000 supports software (SW) RAID. Typical RAID configuration can be done via mdadm in most Linux based operating systems. Contact Kingston for a white paper on recommended RAID configurations.

File system-based RAID is also supported. ZFS zpools can take raw drives, and so can LVM and btrfs. ZFS/LVM have the ability to be booted from (the 4 volumes are bootable). FAQ: DCP1000-05
Most recent Linux kernel versions will work. Rev 2.6.x (Centos 6.6 or 6.7 for example), 3.x, and 4.x for kernel versions have all been validated. The only requirement is that the NVMe drivers be available for the specific version. Most recent Linux OS have NVMe driver support out of the box (Ubuntu 14.04 and later, Centos 7.x and later, etc). Contact Kingston for a full list of supported OS. FAQ: DCP1000-06
In general, a logical approach is to boot from a separate OS drive (a separate SATA SSD for example). Then, use the DCP1000 as a data drive. This configuration enables maximum performance from the DCP1000. FAQ: DCP1000-07
Yes, the DCP1000 can be used as a boot device. The majority of boot configurations for NVMe boot are controlled in the system BIOS setup screen. The recommended configuration is to boot from a separate OS drive (SATA) and use DCP1000 as the data drive. FAQ: DCP1000-08
The DCP1000 offers high performance capability with 7GB/s of sequential performance and over 1 million read IOPS. The DCP1000 is ideal for improving application performance and responsiveness. FAQ: DCP1000-09
The DCP1000 can benefit many applications, including Front End Web, Media Streaming, Email/Collaboration, Data Warehousing, AI/Data Mining, Virtualization/VDI , OLTP Acceleration, Caching Layer, HPC, and others requiring low latencies and high bandwidth. FAQ: DCP1000-10
The DCP1000 give system and storage integrators the ability to offer a differentiated product offering. By deploying the DCP1000 system, integrators can provide a better, faster, and more cost-effective end solution. FAQ: DCP1000-11
You have to create a software-based RAID within your Operating System FAQ: DCP1000-12
Any SW RAID could be used in theory, but RAID 0 and RAID 1 are recommended. RAID 5 is also possible but may have an impact on over endurance of the SSD as parity protection may cause extra writes to the parity drive. FAQ: DCP1000-13
The recommended RAID stripe size for RAID 0 is 256K chunk size. Customers may change this size based upon what is best for their operating environment. FAQ: DCP1000-14
Yes. Intel RST will work with the DCP1000. Intel RST NVMe driver is only supported on some Intel chipsets. Please refer to Intel for more details: FAQ: DCP1000-15
The DCP is a Gen3x8 card, so 8 lanes are recommended. But if deployed into a x4 socket, the DCP1000 will auto negotiate to x4.
If deployed into a physical x8 socket that is electrically lower, it will negotiate to those electrical connections during the learning process (x1-x8). There will be performance loss if used with x4 lanes or fewer. FAQ: DCP1000-16
Yes, NVMe power management commands are supported. Most auto transitions power management settings are disabled by default FAQ: DCP1000-17
5 years – or until the drive’s maximum endurance is consumed. The point where endurance is exhausted is defined as the lowest SSD Life Left reading on any of the 4 internal data drives showing a 1. FAQ: DCP1000-18
The DCP1000 runs from 12V power only, provided from the PCIe socket. DCP1000 has an optional AUX power cable that can be used if a motherboard cannot supply sufficient power (this situation is rare). Almost all systems provide sufficient power directly from PCIe sockets. Please contact Kingston if this is an issue. FAQ: DCP1000-19
No. Only a single power mode is supported. But NVMe Power Management (PM) commands are supported – auto PM is disabled by default. FAQ: DCP1000-20
28% across all DCP1000 capacities. FAQ: DCP1000-21
No. The OP area comes preset at the factory at 28%. FAQ: DCP1000-22
No – this is not required as this will lower the SSD performance. The DCP1000 supports Power Foss (Pfail) protection so data that is ack’ed by the DCP1000 will be flushed to cache in the event of sudden power loss. Write cache should be left enabled. FAQ: DCP1000-23
Kingston provides bench mark scripts for testing DCP performance. The script test for both throughput and IOPS. Kingston can provide a long and short test script with instructions. Please contact your Kingston representative for more information. FAQ: DCP1000-24
Yes, the DCP1000 support auto thermal protection. In case the operating environments reaches above 80 degrees Celsius (drive temperature – not heat sink temperature) – the drive will begin to thermal throttle. FAQ: DCP1000-25
Performance will throttle by 63MB/degree for read and 50MB/degree for writes. FAQ: DCP1000-26
The setpoint is at 80C based on the controller’s built-in temperature sensor for both triggering and restoring performance. FAQ: DCP1000-27
SMART attributes can be viewed through Kingston’s SSD Storage Manager Software or any standard SMART tools can be used to access the SMART data on a per M.2 basis. SSD Life Left for warranty purposes is based on the single worst drive usage. FAQ: DCP1000-28
NVMe format will erase all the data from the device. The data is non-recoverable after a format – all user data will be lost.After the format, the device will return to FOB (Fresh Out of Box) type performance for a limited time. Over time, as the drive is written to, it will return to its steady state performance. FAQ: DCP1000-29
Yes, Kingston has a hardware and OS compatibility list. FAQ: DCP1000-30
No, the DCP1000 does not support variable sector size. (i.e. 520, 528, 4104, 4160, 4224 bytes) FAQ: DCP1000-31
