I had considered purchasing the new version of the DS1813+ (possibly called a DS1815+), but that model has not been released yet, probably would have the same Intel CPU model as the DS415+ (the DS1812+, 1813+, and DS412+ all have essentially the same CPU model), and likely would have had a higher electric wattage consumption compared to the DS415+ if I filled all drive bays. The DS415+ was bought to take the place of a DS212+, whose CPU simply cannot keep pace with 15+ high definition security cameras feeding the NAS with motion triggered video clips via FTP. None of the other DiskStations have experienced lockups during an attempted reboot (or any other lockups that I am able to recall). There have been issues with the DiskStation DS412+ locking up roughly 90% of the time that a reboot is attempted through the web-based DSM, resulting in a blue flashing light on the front console that could only be fixed by pulling the electrical power cord (note that it is usually possible to kill phantom connections from the DSM interface, if that interface will display, so that a reboot is typically not required to recover from the “remembered” connections). This connection “remembering” issue causes a situation where client computers attempting to connect for Windows file sharing are denied access to the server, but the problem also affects the web-based access to the Synology DSM operating system. Eventually, all of the permitted client connections become “in use” due to the Synology sometimes remembering FTP connections long after the security cameras have forgotten about those connections. That said I have experienced occasional problems with most of the NAS units that provide FTP services to security cameras. Most of the Synology NAS units are configured primarily as FTP destinations, although the units also provide one or more Windows shares to network computers using either Active Directory integration or Synology Diskstation internal user accounts, as well as offering network time protocol (NTP) services (to security cameras, Active Directory, and/or a PBX system), and Nagios network monitoring.įor the most part, the Synology NAS units have been very reliable. I have previously purchased and implemented Synology Diskstation DS1813+, DS412+, DS214+, DS212+, DS213j, and DS112j units, so Synology network attached storage (NAS) devices are not entirely new to me (I also have experience with administering various Linux and Windows servers). Part 1: Reviewing the Synology DS415+īelow is my review of that NAS, as posted on Amazon: One of those busy (non) work items is setting up a Synology DiskStation DS415+ NAS with four 6TB hard drives. I have been busy with a lot of items that are completely unrelated to Oracle Database. It seems that lately I struggle to find time to post interesting items to the blog, which is mostly focused on Oracle Database notes, so this is a three in one off-topic post. As frequent readers of this blog likely know, I have not posted very many articles recently.
