Product Information

Memory Upgrade Modules (Ranging from 4GB to 16GB and 32GB Individual Modules – Link below for Tested RAM modules from Crucial, Kingston, Samsung, Timtec and Synology Official Memory too: Here is a link to my favorite UPS (that I own). If you’d like to buy a UPS but spend a little less, here is another great option which has USB data transfer as well so it can automatically turn off your NAS! Here are some other Synology NAS UPS options.

Looking at standard deviation, our HDD configuration recorded 23.27ms to 578.69ms in SMB and 16.67ms to 321.66ms in iSCSI, while our SDD configuration posted 0.45ms to 21.57ms (SMB) and 0.48ms to 6.39ms (iSCSI). 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. Compared to the fixed 16 thread, 16 queue max workload we performed in the 100% 4K write test, our mixed workload profiles scale the performance across a wide range of thread/queue combinations. In these tests, we span workload intensity from 2 thread/2 queue up to 16 thread/16 queue. With HDD throughput, SMB posted a range of 344 IOPS to 385 IOPS while iSCSI hit a range of 575 IOPS to 1,839 IOPS. Using SSDs, iSCSI was by far the best configuration with 8,813 IOPS at 2T/2Q and finishing off at 47,941 IOPS at 16T/16Q. After setting up a Synology NAS, most people are interested in accessing their NAS from outside of their local network.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.

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. Enable UPS support and select the UPS type that you own. You can then configure the time before your NAS enters safe mode. 2.6 How to Setup Notifications on a Synology NAS This next section will determine how much of the volume you’d like to allocate. Generally, most people will use all of it, so you can select Max.If you’d like to use something smaller, you can enter the value. A wizard will then start to assist you in the creation of the scheduled task. Give your report a name, set a schedule, and then specify the total number of reports you’d like to keep.

We then had to make a second volume to use the rest of the pool space. WD Gold HDD 22TB Specifications Model Number As usual, we used the DSM Storage Manager app to manage the WD Gold populated-DS1821+. It also makes it incredibly easy to set up RAID, pools, and volumes as well as to view the health of the drive. In average latency, the 22TB WD Gold was able to reach read and writes of 778.4ms and 174.4ms, respectively, in SMB, while iSCSI posted 49.2ms read and 169.1ms write.That amount is enough for general usage, but a memory upgrade is a must if you want to get the most out of the server. Synology hardware upgrades: Here's my new Synology DS1821+ and the upgrade parts, including a 10Gbps PCIe add-on card, a 32GB DDR4 RAM kit, and two 1.92GB Seagate IronWolf NVMe SSDs. 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 In 4K average latency (where lower is better), the Synology DS1821+ posted 165.11ms write and 429.74ms read in SMB, and 162.92ms write with a much lower 61.63ms read in iSCSI (HDD configuration). Using SSDs, the latency fell to 6.62ms and 9.77ms write/read in SMB and 6.85ms and 2.56ms write/read in iSCSI. 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 For our standard deviation latency results, the 22TB Gold hit 14.04ms through 408.46ms (SMB) and 16.83ms to 245.49ms (iSCSI).

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. Our next benchmark measures 100% 8K sequential throughput with a 16T16Q load in 100% read and 100% write operations. Here, the DS1821+ was able to reach 51,118 IOPS write and 56,348 IOPS read in SMB and 52,857 IOPS write, and 57,085 IOPS read in iSCSI (HDDs). In our SSD configuration, the Synology NAS recorded a minor improvement with 53,992 IOPS write and 56,436 IOPS read in SMB. We saw the best performance using iSCSI with writes and reads of 56,181 IOPS and 57,101 IOPS, respectively. 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.While we went through the initial Synology NAS setup process, there are many additional items you can use your NAS for. I have a bunch of tutorials that I will link below showing how to complete certain actions. Keep in mind, there are a ton of apps you can install and these are my favorite Synology NAS apps that you can install! 4.1 Accessing your Synology NAS Outside of Your Local Network

You shouldn’t open ports to applications you aren’t actively using. For example, you might have SSH enabled, but it’s a good idea to turn off SSH when you’re done and to remove the “allow” firewall rule.

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: However, the appropriate caching size depends on the server's storage volume that you want to cache. The Storage Manager app's SSD Cache Adviser function will give you a good idea of the cache size. 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 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.
