ssd_max_throttle vs IT governance
Wednesday Jul 29, 2009
Chris and I had a short IM exchange yesterday regarding a customer visit I made on monday, its a customer we have both worked with a lot over the years. One of the significant contributory factors of the reported problems is that a line of the form
set ssd:ssd_max_throttle=32is missing from /etc/system across the estate attached to a particular SAN. Common problem, easy diagnosis, etc.
I made the comment that a co-worker of ours in a different part of the organization would have picked up on the need to address the underlying IT governance issue.
I liked this definition from Wikipedia :
Specifying the decision rights and accountability framework to encourage desirable behaviour in the use of IT.and the cause of the cause of the cause of the cause of ssd_max_throttle not being set was in the structure of the established decision rights and accountability framework.
Still, far easier to stick ssd_max_thottle=32 in /etc/system and leave these battles to others this time round. However, an awareness has been sparked.
