Some of the SAS (this is a fast computer interface similar to SATA) disks we received together with the servers that we run osm.ch and related services on, have failed due to old age, and while we originally had an ample supply of spares now we’ve now run out.
Unfortunately, these disks are rather expensive to purchase new, if not to say uneconomic. Luckily Metanet has now helped us out by donating eight 2nd hand disks from their stock. This will allow us to defer a complete replacement for at least 1 to 2 years and make an unhurried decision on what to buy.
A big thank you to Metanet for supporting the Swiss OpenStreetMap Association.
