The latest beta of the server version of Microsoft’s forthcoming Windows 8 operating system includes a handy tool related to the new data deduplication feature. DDPEVAL will test a given dataset using the new deduplication and compression engine and report the savings to be expected. And it works even on non-Windows 8 systems!

Last week I posted the excellent news that the Robocopy in new versions of Microsoft Windows is multi-threaded and thus much (much!) faster. Then I tried to actually use it on a Windows Vista machine. Redmond, we have a problem. It turns out that only the “6.1” versions of Microsoft Windows (Windows 7 and Windows Server 2008 R2) include multi-threaded robocopy.
Robocopy is the best tool to move data between NTFS filesystems but was never very quick. Windows Vista, Windows Server 2008, and later versions include a new version of Robocopy with performance tweaks including multi-threading that speed things up dramatically.
Ever since Microsoft and Intel declared that the combination of Windows and Nehalem could deliver over a million iSCSI IOPS, I’ve been curious about just how they did it. What black magic could push that many I/Os over a single Ethernet connection? And what was on the other end? Now Intel has revealed all in a whitepaper, and the results are surprising!
What’s the difference between naughty and nice when it comes to IT companies? Microsoft and EMC would definitely not have made the nice list over the last decade, but things are changing. With their competition taking dents in the ongoing battles, Microsoft and EMC just don’t look so bad anymore.
