  • Those Synology units that landed rather abruptly on my doorstep a week ago are now up and running.  16TB of effective RAID-5 or 6 storage each, updated all the way to DSM 6.2.2.  

    Two of the arrays had failed drives and ended up in RAID-5, but I have a couple of spares and may fix that before I start actually using them.

    They're not a particularly powerful model - dual core Atom CPUs and 1GB RAM - but for file storage that will mostly be accessed over WiFi that's not a problem.

    Only remaining problem is that it will take a week or so to copy all my data across.


  • Here's something that might help there: 800 Gigabit Ethernet.  (AnandTech)

    That would cut it down from a week to about ten minutes, yes.  I'm not sure what an 800 Gb network card would plug into, though; that needs PCIe 6.0 levels of bandwidth.

    Interesting note in the article is that a 16-port 400GbE switch from Cisco costs around $11,000.  That's not a lot for that much bandwidth, really.  That's a core switch for hundreds of servers on 10GbE, which would collectively cost a large multiple of $11,000.


  • Micron has introduced QLC flash into the place it least belongs: The datacenter.  Unless they haven't.  (WCCFTech)

    Basically, these are targeted at high performance hard disks - the 10K and 15K RPM models that some people are still clinging to.  A drop-in replacement can deliver two orders of magnitude better random read performance.

    A random I/O workload that could run on a disk drive at all isn't enough to wear out a modern SSD, not even QLC, so this is probably safe.


  • That seems to be about it.  All quiet on the Western Front.  And all the other fronts.


Disclaimer: Nothing makes your day off fly by like having to update four servers through seven software revisions, one patch level at a time.

Apple pies are delicious. But never mind apple pies. What colour is a green orange?
