Product Information

By default, the recycle bin will retain files until you empty it. However, there’s an easy way to set up a schedule so that your NAS automatically deletes these old files after a certain period of time. The more is always, the better in terms of capacity, but generally, you won't need drives larger than 250GB for caching. Retention: Select how many snapshots you’d like to retain. Depending on the file type (and size), you’ll most likely have different retention policies for different folders. As we indicated above, we previously review the WD Gold 22TB inside the Supermicro server; however, for these sets of benchmarks, we installed eight of them into our Synology DiskStation DS1821+ configured in RAID6. We will be testing in both iSCSI and SMB protocols.

Now that a storage pool, volume, and shared folder are created, we need to change a few settings to protect and monitor our data. 2.1 How to Setup a Data Scrubbing Schedule on a Synology NAS PCIe-tilføjelseskort, udvidelsesenheder og lagerdiske sælges separat.

Oprettelse af M.2-lagerpulje understøttes kun på SSD'er, der er verificeret af Synology, og som har været igennem omfattende test under ekstreme temperaturforhold. De termiske parametre for SSD'er og NAS-systemet er blevet finjusteret for at sikre, at den termiske tilstand håndteres korrekt i et I/O-intensivt miljø. ( Få mere at vide)With average latency at 8K 70/30 using a Synology DS1821+, the 22TB Gold 22TB posted 11.26ms through 619.27ms in SMB, while iSCSI recorded a range of 7.57ms through 150.39ms. So on the Xfinity/Comcast IPv6 thing. Before three days ago when “they changed things” during an 0200-0430MST (local) outage… IPv6 worked. In the first of our enterprise workloads, we measured a long sample of random 4K performance with 100% write and 100% read activity. Looking at IOPS, the Synology DiskStation DS1821+ HDD configuration recorded 1,550 IOPS write and 595 IOPS read in SMB, while hitting 1,575 IOPS write and 4,153 IOPS read in iSCSI. With SSDs, it showed, expectedly, significant gains (as is the case in the rest of the performance review) with 38,633 IOPS write and 26,209 IOPS read in SMB and 37,339 IOPS write, and 99,988 IOPS read in iSCSI. Considering you can find hard drives of 20TB and higher capacities nowadays, the number of drive bays is not that important. So, if one can live with fewer bays, the DS1821+ has nothing to justify the more expensive cost compared to the DS1621+.

With that, let's proceed with the upgrade. For this post, I did the upgrades on a DS1821+, but the processes and parts are the same on a DS1621+. Synology DS1821+: RAM upgrade Our Enterprise Synthetic Workload Analysis includes four profiles based on real-world tasks. These profiles have been developed to make it easier to compare to our past benchmarks, as well as widely-published values such as max 4K read and write speed and 8K 70/30, which is commonly used for enterprise drives. For our testing, we configured the Synology DiskStation DS1821+ in RAID6 in both iSCSI and SMB using both an HDD and SSD configuration using the following drives: As data requirements grow, so do the expectations of our customers for a solution that can meet the ever increasing performance and capacity requirements," said Julien Chen, Synology Product Manager. "The DS1821+ is specifically designed for customers wanting a versatile storage solution, even in demanding multi-user environments."
