IBM introduces the FlashSystem C200 storage system, which uses a large SLC cache to provide TLC-like durability at a reduced cost.

IBM has introduced the FlashSystem C200, a high-capacity flash storage system aimed at replacing traditional hard disk drives (HDDs) in enterprise environments. The device offers a raw capacity of 1.1PB and an effective capacity of 2.3PB, while achieving a performance of 200,000 input/output operations per second (IOPS). The flash solution is designed for files, backups, and sequential workloads that can tolerate higher latency.

IBM presents the C200 as a more budget-friendly alternative to flash storage, focusing on efficient and cost-effective usage. The proposal highlights integration with IBM's Storage Virtualize, facilitating seamless migrations as it integrates into a FlashSystem network.

The system comprises FlashCore modules (FCMs), with the Gen 4 version providing 46TB of raw capacity through a pseudo-SLC frontend to NAND QLC. With a processor featuring 32 Xeon cores and a 256GB cache, it achieves a latency of 1-2 ms and performance of up to 200,000 IOPS, along with a data transfer rate of 23GBps. Its fixed configuration includes 24 slots, concentrating the raw capacity in a 2RU chassis, all supported by continuous hardware-assisted compression.

The C200 is also equipped with eight 10GbE ports and optional variants that include 16 ports of 32Gb FC/NVMe-FC or 8 ports of 25/10GbE NVMe-TCP. IBM claims its performance is ten times better compared to HDD or hybrid solutions, making it an ideal option for sequential workloads.

Projections suggest that the cost of flash storage will continue to decline, bringing it closer to NL-SAS prices. With the industry exploring flash units of 300, 500, and even 1PB, magnetic platter technologies are expected to face challenges in competition. The suggested retail price of the FlashSystem C200 for end-users is $381,000, which is considered a "respectable" value, and it is expected to be available worldwide starting March 21.
