Med referens till artikeln i IDG http://www.idg.se/2.1085/1.403348/serverrack-ska-radda-jatte-i-kris . Nöden är väl ändå uppfinningens moder? Trots alla stora och återkommande framsteg som skett genom åren på prestandasidan i form av minne, cpu och format, har väldigt lite hänt på själva plattformssidan. En server anno 2001 är väldigt lik en server idag. Administration och automation av infrastruktur har […]
We make extensive use of Hyper-V within Basefarm and I recently encountered a strange problem when doing maintenance on a 5 node windows cluster running the hyper-v role. For reasons I won’t bore you with here (pre-production testing basically), I had been evicting and adding nodes to my host level windows cluster, but when trying […]

I’ve written previously about the dangers of VLF fragmentation, but the problems I’ve actually experienced before were always related to log based operations, i.e. recovery phase after a crash or database mirroring, but last week I saw an alternate issue where doing a full restore from IBM Tivoli Storage Manager (TSM). At the start I […]
In Part 1, I looked at how one could identify that a large blocking chain was causing resource exhaustion in SQL Server leading to a cluster failover. Being as we were working retrospectively, we were lacking data to analyse what actual condition was causing the blocking chain to begin with. This post address that area […]

At this level we take full responsibility for the operations of the infrastructure but also the customer developed applications and […]
Here at Basefarm we run a large number of 24×7 business critical systems for our customers. So when one of our windows customers recently encountered an unexplained SQL Server crash on one such system, it was something that got our highest attention.
