64-layer TLC paired with NVMe for the datacenter has arrived with the promise of more capacity, lower cost and better performance than ever before. Intel's DC P4510 improves on Intel's DC P4500 Series that pairs 32-layer TLC flash with the NVMe interface.
NVMe is architected from the ground-up to remove legacy layers of hard drive interfaces, taking full advantage of the speed and parallelism of solid state nonvolatile memory. NVMe lowers overall CPU overhead because NVMe has a simplified command set which minimizes the number of CPU clocks per I/O which increases QoS in comparison to AHCI.
NVMe is designed to be future-proof, with a protocol built for current and future non-volatile storage solutions. Previous AHCI interfaces supported only one SQ/CQ (Submission Queue/Command Queue), NVMe supports up to 64K separate SQ/CQ's.
Intel's 64-layer TLC NAND technology enables the DC P4510 to offer double the capacity of the DC P4500 Series and quadruple the capacity of Intel's DC P3520 Series.
Higher density enables cloud service providers to increase the number of users per rack, improve data service levels, and at the same time greatly reduce power usage and datacenter footprint.
In addition to doubling the capacity of the DC P4500, the DC P4510 powered by Intel's Gen2 64-layer 3D TLC flash offers vastly improved performance.
Comparing the DC P4500 to its successor the DC P4510, reveals a 90% improvement in sequential write bandwidth at the 2TB capacity point. The DC P4510 delivers up to 2x better write IOPS per TB of flash and Quality of Service (QoS) is up to 10x better than its predecessor.
The DC P4510's management and serviceability are both greatly improved over previous generations. For serviceability, Intel spent a lot of time and resources to get LED light management right. This allows for quick and easy identification of drives that need servicing. The DC P4510's U.2 form-factor also enables hot-swap capabilities that are not possible with other NVMe form-factors.
Improvements made possible by Intel's 64-layer flash technology enable the datacenter to do more per server. The DC P4510 delivers 12x the IO workload scaling of the DC P4500 at the same QoS.
Enhanced SMART monitoring and a power-loss imminent (PLI) protection scheme minimize service disruptions. End-to-end data path protection guards against silent data corruption. Additionally, the DC P4510 has onboard host power-loss protection via an integrated capacitor that provides enough power to flush in-flight data to the NAND array in the event of host power-loss.
On the data security front, the DC P4510 Series provides TCG Opal 2.0 and AES 256-bit hardware encryption features.
Intel's DC P4510 Series is built for cloud storage architectures where read-intensive performance is the most critical consideration. Armed with 64-layer TLC flash, the DC P4510 delivers more bandwidth, better QoS, and overall performance than its predecessors.
Since the introduction of NVMe, Intel has really been driving home the importance of low queue-depth performance.
This chart shows the distribution of queue depths for a few sample datacenter workloads measured in the Intel environment to illustrate examples of the operating region. Random Mixed workload represents common enterprise use case.
Performance at low queue depths is the most important performance metric in the majority of usage scenarios in both the consumer and enterprise space. The DC P4510's performance reflects this focus as you will see when we get into the numbers.
Intel's DC P4510 is the first TLC-based NVMe enterprise SSD that we've had a chance to test, let's see if it can keep up with its MLC counterparts.
The Intel DC P4510's we have on the bench today sport the following hardware and steady-state performance specifications: 4K Random Read / Write = up to 637K/189.5K. Sequential Read/Write = up to 3,200/3,000 MB/s. Power consumption = 12-16W Active/5W idle. Controller = Intel NVMe controller. NAND = Intel 3D 64-layer 3-bit. Data DRAM Cache = 1GB per TB. Onboard Power-loss Protection = Yes. Intel warrantees the DC P4510 for 5-years or TBW threshold, whichever comes first.
