Sun's Niagara 3, a one billion-transistor, 16-core processor, and the IBM POWER7 are the subject of Jon Stokes's Ars Technica piece that introduces readers to the floorplan of both chips.
The basics of flash memory are the topic of a blog entry in The Zone Manager. Engineer Brad Diggs attempts to explain why flash through the ZFS secondary cache, or L2ARC, and ZFS Intent Log (ZIL) can improve overall directory performance. He also asserts the use of flash memory and ZFS will enable "radical" new directory services architectures, and explains further in a secondary posting.
Are the advances in Intel processor design edging SPARC processors out of the marketplace, asks Karim Berrah in a recent blog entitled "SPARC or Intel?" He offers some points of comparison that result in a necessarily ambiguous conclusion, as each processor has advantages in its favor, according to him.
The Sun Flash Accelerator F20 PCIe Card is a Flash PCIe card with an integrated disk controller that increases server storage I/O and application performance. Targeted at I/O intensive applications, such as databases with 4K block aligned workloads, the Sun Flash Accelerator delivers I/O performance equaling that of up to 300 disk drives, Sun reports.
The Sun Flash Accelerator F20 PCIe Card is part of the Sun's FlashFire product family. It delivers up to 96 GB of solid-state disk capacity and 100K IOPS without consuming any disk slots. It also provides 87,000 write IOPS at 4k. The card contains a super-cap to ensure that there is power to write down the caches to the flashes.
