After Samsung’s SmartSSD, it’s IBM flip to reveal that it’s engaged on an enterprise storage answer based mostly by itself proprietary know-how. It is known as FlashCore Module 2 (or FCM2) and marries some very previous ideas (as previous as computing itself) with some innovative options in an SSD.
The latter comes within the form of Everspin’s magnetoresistive RAM (MRAM), which offers an inherently non-volatile write cache that’s as quick as system reminiscence present in smartphones or computer systems.
The opposite vital transfer is using 96-layer QLC quite than 64-layer TLC, which is perhaps a step too far for purists who consider QLC doesn’t supply sufficient endurance/knowledge retention.
As for the old-turned-new idea, FCM2 compression is much like Doublespace in MS-DOS or compression software program Stacker (keep in mind that?).
Once more, right here, Large Blue makes use of know-how that comes from its IBM Z mainframe line; line-rate clear compression permits it to realize a mean compression ratio of about 2.28:1, in comparison with 2.5:1 for LTO tape and three:1 for Samsung’s SmartSSD.
IBM will ship FlashCore modules with capacities starting from 4.8TB to 38.4TB, with rated compressed capacities between 11TB and 88TB. Provided that Micron has introduced 178-layer NAND with 200+ layers on the horizon, FC modules with capacities past 100TB are inside the realms of risk.
IBM’s FlashSystem storage home equipment can pack as much as 24 drives in a 2U rack, providing as much as 0.76PB native capability with a throughput of 40GBps. A 42U cupboard ought to subsequently ship a complete capability of 12.13PB, albeit with a watch watering price ticket.
