We have a number of "Strongway 2-Speed Hydraulic Rapid Lift XT Table
1000-Lb" carts, which are the scissor lift type.
They're sturdy. They double as simple moving carts (hauling a stack of
servers to surplus) or frequently used as a small, mobile work table
wherever needed within the datacente
To provide my anecdote, I happen to have this one:

Pros:
I didn't have to choose it, it was already there when I inherited this
server room
It is compact and easy to maneuver down the aisles, you can even turn it
around
As Paul says - start a subnet manager. I guess you are using the distro
supplied IB stack?
Run the following commands:
sminfo
ibdiagnet
these will check out your subnet manager and your fabric

Oh you will also need a IB subnet manager (opensm) running since you
have an unmanaged switch. You can start this on one of the compute
nodes. I would probably start up 2 so you have redundancy.

Generally OpenMPI will be able to autodetect much of the IB setup you
just need to make sure you have UCX. With modern OpenMPI you will need
to build a version of PMIx to hook into Slurm. Slurm will also need to
be built against PMIx as well for best experience. Thus in terms of

Hi All,
We bought a Server Lift "SL-1000X Super-Duty Lift" last year.
https://serverlift.com/data-center-lifts/sl-1000x/
It's powered by a large 12V battery, and uses what looks like a car
winch to move the platform.
The powered functionality is useful, and very nice when you are tired,
but
I have recently acquired a few ConnectX-3 cards and an unmanaged IB switch
(IS5022) to upgrade my department's beowulf cluster.
Thus far, I have been able to verify that the cards and switch work via the
MFT and opensource tools in ubuntu,
Though, I was wondering if anyone knew of any guide or r
The engine hoist is just superb! The right tool for the job.
Thinking about this, old style factories had overhead cranes. At Glasgow
University we had a cyclotron, and I am told one of the professors took a
great joy in driving the crane.
The Tate Modern art gallery has a huge overhead crane, kept

We had an electric scissor lift in the DC, and exactly that happened -
battery died. More expensive to replace than buying a new lift.
So we got a manual one (making sure it can go to full rack height which
is very useful) - much less likely to go wrong.
