Synology DX517 5 Bay Desktop Network Attached Storage Expansion Enclosure, Black

Product Information

SSD cache can be enabled by using 2.5" SATA SSD drives in standard drive bays or without occupying drive bays by installing Synology SNV3400 Series M.2 NVMe SSD drives through the built-in M.2 slots. SNV3400 Series M.2 NVMe SSD drives can also be used to create SSD storage pools. Drives are sold separately. Performance figures are obtained through SMB sequential throughput tests using Windows Server 2016 Datacenter on a I currently have all of my media on volume1. I’ve heard/read that trying to span volume1 across the DS918+ and DX517 is a recipe for disaster, so if I get a DX517 expansion unit would I be able to put new media on volume2 and have Plex/Sonarr/Radarr play nice with the new storage pool? Usable capacity for each volume will be lower than the maximum volume size and is dependent on the filesystem and the amount of system metadata stored. Need Help? Been quoted elsewhere?

The performance of the mail system will slightly decrease in high-availability mode due to data synchronization between the two servers. Please select Synology memory modules for optimum compatibility and reliability. Synology will not provide complete product warranty or technical support if non-Synology memory modules are used for memory expansion. Extend the standard 3-year hardware warranty of your DS1821+ with 2 more years of Synology-certified support and premium services that help you recover faster in the event of disaster. Figure 3. Synology DS918+ NAS (left) and DX517 expansion unit. The DX517 attaches to the DS918+ via an eSATA cable. Managed from DiskStation Manager on the host NAS, the additional bays in the DX517 are immediately ready to be used once connected. On-the-fly volume expansion ensures that storage and services on the host are not interrupted during volume expansion.I have a DS918+ with 4x8TB WD White drives in a SHR1 array that is running out of space. I’m not looking for opinions about the efficacy of SHR1 vs SHR2 vs the various RAID arrays. My question is specific to Plex as I use my NAS primarily as a Plex media storage device. During testing, the maximum number of SSDs supported by this model is installed in a RAID 5 configuration. In two years time, the NAS's 45% storage vacancy had dwindled to 19%. I thought it would be wise to proactively increase storage space. My first thought was to replace the DS918+ with a Synology eight-bay DS1819+ equipped with 10 TB Western Digital Red drives. Given the high cost of the DX517 (and I presume its rumored, impending replacement will be about the same), I'm wondering what people are using it for. I see some posters noting that they have two, or even three of these expansion units. You can save a few hundred dollars over another NAS unit, and I suppose you don't need to deal with more configuration, but why put money into a DX517 instead of larger drive sizes? PCIe add-in cards, expansion units, and storage drives are sold separately. Refer to the compatibility list for compatible devices.

I made what seems to be a common mistake (given other posts here) and assumed that the DX517 expansion unit would seamlessly give me another five drive bays for when I was ready to expand. I have accumulated a number of hard drives in the process of upgrading and like the idea of putting them to use, but in reading about the DX517 it seems it'd be fine to create a second storage pool, but it's extremely risky and poor practice all around to spread your volume between the drives in the main NAS unit and drives in the expansion unit. This sub has talked me out of that idea - I don't want to risk it. Seamless transition between clustered servers in the event of a server failure to minimize the impact on applications. I have not noticed any speed or performance differences when loading files into the expansion unit or when streaming video from the expansion unit. My Synology DS918+ NAS was set up in February of 2018 with four 8 TB Western Digital Red drives. My video collection took up 17 TB (55%) of the available 30.7 TB of storage. I assumed the 13.7 TB of free space would last a long time (years) since I only buy a few titles per year. At the time of initial installation, my video collection was 71% DVDs, 29% Blu-rays, and 0% 4K Blu-rays.SMB1 (CIFS), SMB2, SMB3, NFSv3, NFSv4, NFSv4.1, NFS Kerberized sessions, iSCSI, HTTP, HTTPs, FTP, SNMP, LDAP, CalDAV

Tested on an all-flash volume with Synology SAT5200 flash drives.Synology DS1621+ is a powerful and compact 6-bay network attached storage solution designed to store and protect critical data assets. Today’s growing amount of unstructured data requires smarter and increasingly higher performance methods of storing, accessing, and collaborating. Designed for scalability, the DS1621+ enables you to start small, then expand as your data grows. Anyway, i want to strictly separate the hdd's / storage from the expansion unit from the storage of the NAS to prevent data loss caused by NAS or DX failure. For example if the NAS or DX Powersupply fails or one of them just stops working, the RAID will be damaged, because suddenly several disks disappear at the same time. This is why i want to separate them. Unfortunately, it is not clear to me how to set it up the right way. I am not sure, if i have to create a separate storage pool with its own volume(s) for the new disks in the expansion unit, or if it will be enought to simply add the disks to the existing storage pool and create a new volume within this storage pool? I think the second option (adding drives to existing pool and creating a new volume in there) will distribute the data from volume 1 and 2 which are in the same storage pool, across all HDD's (These in the NAS and DX517) and will not separate them physically on the Harddrives, right? Performance figures are obtained from testing conducted with the device fully populated with drives under a continuous recording setup. Actual system capabilities may vary based on configuration, drive performance, enabled features, and the presence of additional workloads. I am currently using only two of the DX517's five bays, for a total storage of 46 TB across six 8 TB drives, and a total occupancy of 25 TB (54%). Each 8 TB drive has 7.676 TB storage available. The NAS's operating system reserves 0.324 TB of space on each drive. Filling the remaining three bays with 8 TB drives would provide 69 TB total storage with a currant occupancy rate of 36%.
