What reduces risk … a great engineering and support team, or a brand name ?

I’ve written about approved vendors and “one throat to choke” concept in the past. The short take from my vantage point as a small, not well known, but highly differentiated builder of high performance storage and computing systems … was that this brand specific focus was going to remove real differentiated solutions from market, while … Read moreWhat reduces risk … a great engineering and support team, or a brand name ?

pcilist: because sometimes you really, really need to know how your PCIe devices are configured

If you don’t know what I am talking about here, that’s fine. I’ll assume you don’t do hardware, or you call someone else when there is a hardware problem. If you think “well gee, don’t we have lspci? so why do we need this?” then you probably have not really tried to use lspci to … Read morepcilist: because sometimes you really, really need to know how your PCIe devices are configured

Architecture matters, and yes Virginia, there are no silver bullets for performance

Time and time again, the day job had been asked to discuss how the solutions are differentiated. Time and time again, we showed benchmarks on real workloads that show significant performance deltas. Not 2 or 3 sigma measurements. More often than not, 2x -> 10x better. Yet … yet … we were asked, again and … Read moreArchitecture matters, and yes Virginia, there are no silver bullets for performance

I don't agree with everything he wrote about systemd, but he isn't wrong on a fair amount of it

Systemd has taken the linux world by storm. Replacing 20-ish year old init style processing for a more legitimate control plane, and replacing it with a centralized resource to handle this control. There are many things to like within it, such as the granularity of control. But there are any number of things that are … Read moreI don't agree with everything he wrote about systemd, but he isn't wrong on a fair amount of it

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

A wonderful read on metrics, profiling, benchmarking

Brendan Gregg’s writings are always interesting and informative. I just saw a link on hacker news to a presentation he gave on “Broken Performance Tools“. It is wonderful, and succinctly explains many thing I’ve talked about here and elsewhere, but it goes far beyond what I’ve grumbled over. One of my favorite points in there … Read moreA wonderful read on metrics, profiling, benchmarking
