Optical Breakthroughs Eyed for Storage: Page 2 of 2

Researchers say the new technology will show up first as a way to interconnect servers or supercomputers, since a board-level solution will take a couple of years more to commercialize. But the introduction of a working prototype is a key first step.

Elsewhere, other vendors made announcements that also could affect the storage industry, albeit in the long term:

  • Avago demonstrated optical components for 17-Gbit/s Fibre Channel at the show. The demo uses Avago's VCSEL and SERDES technologies. The vendor also showed components operating at 40 Gbit/s and 100 Gbit/s.
  • Hitachi and Opnext announced a demonstration of fast lasers designed to support 100-Gbit/s Ethernet, which is being discussed in the IEEE's 802.3ba task force. Low power is a feature: The demonstrated 25-Gbit/s 1310-nm CWDM EA-DFB lasers were achieved based on Hitachi’s advanced technology for uncooled and high speed lasers which has already been demonstrated in previous work of uncooled 10-Gbit/s and cooled 40Gbit/s EA-DFB lasers,” said Masahiko Aoki, Central Research Laboratories, Hitachi, Ltd., in a prepared statement. “We believe that uncooled operation is the key to achieve small and low cost 100 GigE transceivers for LAN application.”

At least one analyst sees these steps as part of a larger progression. "Optical is a great approach for boosting performance, lowering latency, and spanning distances, particularly when it's done in an energy-efficient manner," says Greg Schulz of the StorageIO Group. "In the case of IBM, if the technology can be applied down the road in a cost-effective manner to reduce power and cooling on a processor or computer or in chip-to-chip applications, to say that would be a benefit would be an understatement."

Other demos of faster data rate technologies herald better support for data protection and resiliency, as well as making the Internet generally faster to support more activity, Schulz says.Have a comment on this story?
