Raw Unapologetic Firepower: kdb+ from @Kx

While the day job builds (hyperconverged) appliances for big data analytics and storage, our partners build the tools that enable users to work easily with astounding quantities of data, and do so very rapidly, and without a great deal of code. I’ve always been amazed at the raw power in this tool. Think of a … Read moreRaw Unapologetic Firepower: kdb+ from @Kx

Systemd and non-desktop scenarios

So we’ve been using Debian 8 as the basis of our SIOS v2 system. Debian has a number of very strong features that make it a fantastic basis for developing a platform … for one, it doesn’t have significant negative baggage/technical debt associated with poor design decisions early on in the development of the system … Read moreSystemd and non-desktop scenarios

Talk from #Kxcon2016 on #HPC #Storage for #BigData analytics is up

See here, which was largely about how to architect high performance analytics platforms, and a specific shout out to our Forte NVMe flash unit, which is currently available in volume starting at $1 USD/GB. Some of the more interesting results from our testing: 24GB/s bandwidth largely insensitive to block size. 5+ Million IOPs random IO … Read moreTalk from #Kxcon2016 on #HPC #Storage for #BigData analytics is up

new SIOS feature: compressed ram image for OS

Most people use squashfs which creates a read-only (immutable) boot environment. Nothing wrong with this, but this forces you to have an overlay file system if you want to write. Which complicates things … not to mention when you overwrite too much, and run out of available inodes on the overlayfs. Then your file system … Read morenew SIOS feature: compressed ram image for OS

It is 2016 … why am I fighting with LDAP authentication in linux? Why doesn't it just work?

Ok … very long story that boils down to us trying to help a customer out. I am trying to avoid the “lets just add another user to /etc/passwd” or similar such thing. And they aren’t quite ready to hook into AD or similar. So we have this issue. I want to enable their nodes … Read moreIt is 2016 … why am I fighting with LDAP authentication in linux?

Not even breaking a sweat: 10GB/s write to single node Forte unit over 100Gb net #realhyperconverged #HPC #storage

TL;DR version: 10GB/s write, 10GB/s read in a single 2U unit over 100Gb network to a backing file system. This is tremendous. The system and clients are using our default tuning/config. Real hyperconvergence requires hardware that can move bits to/from storage/networking very quickly. This is that. These units are available. Now. In volume. And are … Read moreNot even breaking a sweat: 10GB/s write to single node Forte unit over 100Gb net #realhyperconverged #HPC #storage
