Synology DS1821+8bay NAS V1500B Quad-Core 2.2 GHz,Black

Product Information

If you're using the DS1621+ and want to upgrade to the DS1821+ to take advantage of the two extra drive bays, the process is the same as when you migrate from one Synology server to another. 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." More Than Enough Performance Creating M.2 storage pools requires the use of Synology-verified SSDs, which are rigorously tested under extreme temperature conditions. Thermal parameters for SSDs and NAS units are fine-tuned to ensure optimal management of thermal conditions under I/O-intensive environments. ( Learn more) 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.

The Synology DS1821+ is equipped with pretty much the exact same connectivity ports as the 6-bay model; that is, four RJ-45 1GbE LAN ports, two eSATA ports, and four USB 3.2 Gen 1 ports (one more than the DS1621+). Those who want to get the most out of the DS1821+ can utilize its PCIe Gen3 x8 slot (x4 link), which is used to add a 10GbE network adapter card or an additional M.2 NVMe drive slot to further improve performance. While the DS1621+ has a high-performing Intel-based version with the DS1621xs+, the DS1821+ is currently the only model in the line. So on the Xfinity/Comcast IPv6 thing. Before three days ago when “they changed things” during an 0200-0430MST (local) outage… IPv6 worked. At this point, you will need to create rules that allow traffic into your NAS. The first thing you need to ensure is that you allow traffic to DSM. That said, when setting up the Gold HDDs, we actually hit a limitation of the filesystem. There is an upper limit on volume size, so we first had to make a volume with the max size of 103.5TB (as you can see in the image below). 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 NASAs far as performance goes, Synology quotes the DS1821+ around 2.3GB/s read and 1.15GB/s write in sequential speeds using (when using optional aggregated 10GbE connectivity), while random speeds are expected to reach up to 113,000 IOPS read and 54,000 IOPS write (when using 10GbE iSCSI). These numbers are pretty much on par with the DS1621+ model we reviewed last week. Nonetheless, the DS1821+ is able to reach these numbers due to its AMD Ryzen V1500B 4-core 2.2 GHz 64-bit (also inside the DS1621+), which features Hardware Encryption Engine (AES-NI). The above-mentioned performance will slow down a bit when leveraging this technology due to the encryption process. The DS1621+ also can be outfitted with up to 32GB DDR4 ECC SODIMM RAM, though it ships 4GB with the standard build. Give your storage pool a description if you’d like, select the RAID type you will be using and select Next to proceed. Every time a snapshot is created, a “restore” point is created, which allows you to recover files/folders from a point in time. The best part about this is that the snapshots themselves take up very little space and give you tons of flexibility! In any case, installing the SSDs onto the server is super easy. The two M.2 slots are inside the server's left wall. Take the first and second drive bays out, and you can reach them. Synology DS1821+: 10Gbps NIC card upgrade

Certain restrictions apply when adding drives to existing storage pools. Refer to this article for more information.You will need two drives if you want to cache for both writing and reading -- so it's a good idea to get two. Den brugbare kapacitet for hver diskenhed vil være lavere end den maksimale diskenhedsstørrelse og afhænger af filsystemet og mængden af lagrede systemmetadata. Accelerated Performance - 177% higher 4K random read IOPS and 76% faster sequential write speeds compared to its predecessor And finally, the servers have a PCIe slot for an add-on card. In this case, you can use it to add 10Gbps connectivity to the servers -- another must if you're into Multi-Gig. 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.

If you're mulling over the two, that is the only point you should consider. Synology DS1821+ vs DS1621+: Hardware specifications Model While this certainly makes them a perfect fit for enterprise-level data centers, they are also a great choice for SMBs that need to store huge amounts of data and for those who want to future-proof their repository (capacity-wise). So, it made sense for us to see what it is capable of outputting using some of the leading desktop (or SMB) NAS form factors.After setting up a Synology NAS, most people are interested in accessing their NAS from outside of their local network. Data scrubbing inspects your volumes and modifies detected inconsistencies. In simple terms, this protects your NAS against bit-rot. There isn’t a specific schedule that’s mandatory, but it’s a good idea to run it at a minimum, bi-annually. When the drive is unmounted, no one can access the files until you mount the folder again. If you lose the encryption key, your files will be lost forever. Keep it somewhere safe!

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.Our next test shifts focus from a pure 8K sequential 100% read/write scenario to a mixed 8K 70/30 workload, which will demonstrate how performance scales in a setting from 2T/2Q up to 16T/16Q. 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. Next, we need to access and remove the existing memory, as the news 32GB or 64GB of memory for our Synology DS1821+ will occupy both slots.
