Otpakiranje Synology DiskStation DS1621+

DiskStation DiskStation DS1621+ dolazi u jednostavnoj, relativno maloj kartonskoj kutiji, ali to ima smisla jer je sam uređaj vrlo kompaktan.

S prednje strane nalazi se naljepnica s glavnim prednostima DiskStation DS1621+ i slika uređaja, dok na stražnjoj strani imate više tehničkih detalja otisnutih na kutiji.

Pakiranje za Synology DiskStation DS1621+

Unutar paketa možete pronaći DiskStation DS1621+ , adapter za napajanje, dva visokokvalitetna LAN kabela, dva plastična ključa za zaključavanje ladica pogona, paket vijaka (za montažu 2,5-inčnih pogona za pohranu u ležišta za 3,5-inčne pogone) , i brzi vodič za instalaciju.

Dodatna oprema koja dolazi s DS1621+

The traditional approach of Synology towards packaging shows that their devices are oriented towards prosumers and professionals. There are no bells and whistles, but the package includes all the accessories needed to get the DiskStation DS1621+ going.

Specifikacije hardvera i dizajn

DiskStation DS1621+ je kompaktan, s visinom od 6,53 inča (166 mm), širinom od 11,1 inča (282 mm) i dubinom od 9,57 inča (243 mm). S 11,2 lbs (ili 5,1 kg), relativno je težak čak i bez pogona.

Prednji dio Synology DS1621+

Uređaj ima šest ležišta za pogone od 3,5 inča, koji se mogu pojedinačno zaključati priloženim ključevima. Svaki zaljev ima svoje statusno svjetlo. Podržavaju instalaciju bez alata za 3,5-inčne pogone, dok priloženi vijci omogućuju ugradnju i 2,5-inčnih pogona. Pogoni se mogu konfigurirati u Synology Hybrid RAID ( SHR ), Basic , JBOD , RAID 0 , RAID 1 , RAID 5 , RAID 6 , RAID 10 , ovisno o potrebama i broju instaliranih pogona. Naravno, svi diskovi se mogu zamijeniti na vrući način.

Ležišta za pogone omogućuju instalaciju tvrdih diskova bez alata

Na prednjoj strani DiskStation DS1621+ nalazi se gumb za napajanje, statusna LED dioda , ^(LED)LED za upozorenje , kao i četiri LED diode^(LEDs) koje pokazuju status LAN veze za svaki port. Skriven^(Hidden) u donjem desnom kutu, nalazi se USB 3.2 Gen 1 port.

DS1621 DS1621+ ima ukupno tri USB 3.2 Gen 1 porta, s jednim na prednjoj strani

Prelazeći na stražnju stranu uređaja, imamo konektor za napajanje izmjeničnom strujom, Kensington Security utor, još dva USB 3.2 Gen 1 porta, četiri Gigabitna^(Gigabit) mrežna porta (s podrškom za spajanje linkova) i dva eSATA porta. Synology DiskStation DS1621+ također ima PCIe x8 utor za proširenje koji se može koristiti za instaliranje, na primjer, 10GbE mrežne kartice.

Stražnja strana Synology DS 1621+

Unutrašnjost izgleda dobro: četverojezgreni procesor AMD Ryzen V1500B 2,2 ^{(AMD Ryzen V1500B)}GHz s do 32 GB ECC DDR4 (naš je došao sa standardnim 4 GB) čini uređaj prikladnim za lagane virtualne strojeve i multimedijske aplikacije. Fleksibilnost DiskStation DS1621+ dodatno je poboljšana mogućnošću dodavanja dva M.2 2280 NVMe SSD-a^{(NVMe SSDs)} za predmemoriju pisanja. To uvelike povećava performanse čitanja i pisanja i omogućuje pristup većem broju korisnika.

SSD^(SSDs) - ovi su prikladno smješteni u kućištu

RAM je također lako dostupan: trebate samo odvrnuti dva vijka na dnu uređaja i možete zamijeniti ili dodati memoriju. Ipak, oprezno^(Careful) , radi se o ECC DDR4 , pa morate potražiti kompatibilne module.

Samo uklonite dva vijka kako biste pristupili DDR4 DIMM utorima

NAS se hladi s dva ventilatora od 90 mm. Nažalost, dizajn kućišta ne dopušta ugradnju zračnog filtera, pa u prašnjavim okruženjima trebate redovito čistiti uređaj jer će to produžiti vijek trajanja ventilatora. Kada trebate zamijeniti ventilatore, oni su lako dostupni i mogu se zamijeniti sa stražnje strane.

Na Synology DS1621+

DiskStation DiskStation DS1621+ ima potrošnju energije od otprilike 51 W pri pristupu pogonima i oko 25 W kada su pogoni u hibernaciji. Razina buke je niska u normalnom radu, ali ako postavite ventilatore da rade na 100%, bolje bi vam bilo da imate namjensku poslužiteljsku sobu sa zvučnom izolacijom.

Overall, the design is rugged and inspires confidence in the longevity of the product. There are many connectivity options, and the drives are super easy to access and replace, thanks to the tool-less mounting design. Status LEDs ensure that you can get a good idea of the state of the DiskStation DS1621+ without accessing the interface. The focus was on efficiency when designing the device, and it shows.

Postavljanje i korištenje Synology DiskStation DS1621+

DiskStation DS1621+ smo testirali s pet Synology 8TB diskova, koje je bilo vrlo lako instalirati u utore. Također smo dobili dva SSD diska od 400 GB koje smo konfigurirali za predmemoriju čitanja/pisanja. Nakon što ubacite sve pogone, postavljanje hardvera je jednostavno: priključite AC kabel, spojite NAS na usmjerivač pomoću LAN kabela i uključite uređaj.

Sučelju DS1621+ može se pristupiti iz bilo kojeg preglednika

Zatim smo odlučili koristiti najnoviji operativni sustav DiskStation Manager ( DSM 7.0.1 ). Nakon instalacije DSM -a i ponovnog pokretanja, možete konfigurirati podatke za prijavu. Čarobnjak za postavljanje zatim pita želite li instalirati standardne preporučene pakete za vaš NAS ili ih želite sve instalirati. Također možete preskočiti ovaj korak i kasnije ih instalirati ručno. Zatim ćete biti upitani želite li stvoriti QuickConnect ID koji možete koristiti za daljinsko povezivanje s vašim NAS -om putem interneta.

Postavljanje QuickConnect ID- a na DS1621+

Kao što je prije opisano, vaši pogoni za pohranu mogu se konfigurirati za rad u bilo kojem od Synology Hybrid RAID ( SHR ), Basic , JBOD , RAID 0 , RAID 1 , RAID 5 , RAID 6 , RAID 10 načina rada. Što se tiče podržanih datotečnih sustava, možete birati između Brtfs i ext4, iako možete birati između više vrsta datotečnih sustava za vanjske pogone. Konfiguriranje datotečnog sustava i RAID - a bilo je jednostavno kao odabir između nekoliko opcija izbornika. Krenuli smo s konfiguracijom RAID 10 (četiri diska, ukupno korisnog prostora od otprilike 14 TB i redundancije pogona),SSD caching i hot spare (peti disk). Hot spare aktivira se kada jedan od RAID pogona pokvari, a migracija i zamjena se obavljaju automatski, bez potrebe za ljudskom intervencijom.

Konačna RAID konfiguracija, s vrućom rezervom i SSD cachiranjem

Najnovija verzija DSM operativnog sustava izgleda sjajno i dobro je organizirana. Grafičko korisničko sučelje je jednostavno za korištenje i pruža sve potrebne vizualne naznake čak i početnicima da počnu raditi sa Synology DiskStation DS1621+ .

DSM grafičko sučelje je praktično i izgleda dobro

Synology nudi modularni pristup za alate i aplikacije. Nakon što prođete kroz čarobnjak za brzo postavljanje, možete koristiti Package Center za preuzimanje i instalaciju svih alata potrebnih za personalizaciju i korištenje DiskStation DS1621+ u vašem konkretnom scenariju. Centar paketa^{(Package Center)} je u osnovi trgovina aplikacija s rješenjima koje je razvila Synology i aplikacijama provjerenih trećih strana.

• Upravitelj virtualnih strojeva - možete pokrenuti više Windows , Linux ili čak DSM virtualnih strojeva na DS1621+ .

Drugi paketi mogu pomoći da vaš NAS pretvorite u VPN poslužitelj, poslužitelj e-pošte, pa čak i LDAP poslužitelj.

Synology Synology DS1621+ ima modul Virtual Machine Manager

Agregacija veza^(Link) korisna je značajka, ali malo ublažava 1Gbps ograničenja mrežnih adaptera. Pogotovo budući da CPU i datotečni sustav mogu podnijeti veliki broj istodobnih korisnika, ako vam je potreban NAS za više prijenosa datoteka i mislite da ćete biti ograničeni propusnošću mrežnog adaptera, možete kupiti PCIe karticu za proširenje.

Dokumentacija za podršku je lako dostupna i detaljna. U modulu pomoći DSM^{(DSM Help)} -a dobivate informacije o njegovim značajkama, veze na tutorijale, kao i veze na videozapise koji prikazuju potencijal vašeg NAS -a i kako ga postaviti.

Dokumentacija DSM pomoći

Ako ćete DiskStation DS1621+ koristiti u kućnom okruženju, obavezno zakažite redovito održavanje koje uključuje brisanje prašine i čišćenje uređaja, jer nema filter za prašinu. Također, ovisno o opterećenju, ventilatori mogu postati vrlo glasni. Tijekom naših testova nismo uspjeli učitati moćni procesor na više od 60% njegovog kapaciteta, ali šest diskova i dva SSD^(SSDs) - a u tako malom kućištu ipak može dovesti do visokih temperatura. Govoreći o temperaturama, pogoni nikada nisu prešli 98,5 stupnjeva Fahrenheita^(Fahrenheit) (37 stupnjeva Celzija^(Celsius) ) tijekom naših testova. SSD^(SSDs) - ovi su bili samo malo topliji, na 104 stupnja Fahrenheita^(Fahrenheit) (40 stupnjeva Celzija^(Celsius) ).

The Synology operating system is, we believe, the most advanced and user-friendly management system for network-attached storage solutions. We had no trouble setting up the Synology DiskStation DS1621+ and, while we didn’t have enough time to test out each individual scenario, we can safely say that this NAS is a very powerful tool for small businesses and enthusiasts .

Koliko je brz Synology DiskStation DS1621+ pri prijenosu podataka?

Budući da se ipak radi o NAS rješenju, testirali smo brzine prijenosa na i s drugih uređaja na istoj mreži. Rezultati su bili predvidljivi, s obzirom na specifikacije uređaja: korištenjem povezivanja, brzina prijenosa je bila maksimalna na 1032 Mbps za pisanje podataka na DiskStation DS1621+ i 1792 Mbps za čitanje podataka. Ovo je najbolji scenarij, s uključenim SSD predmemorijem i združivanjem veza. Bez agregacije veze, vrijednosti su očito bile niže, jer je propusnost ograničena na 1 Gbps : 916 MBps za pisanje, 906 Mbps za čitanje.

Brzine čitanja sa agregacijom linkova su vrlo dobre

Kada smo onemogućili predmemoriju za čitanje/pisanje koju pružaju SSD^(SSDs) -ovi , bilo je vrlo male razlike u pogledu brzine čitanja s uređaja.

Isključivanje SSD predmemorije ima mali učinak na uzastopne prijenose

Ovaj rezultat je očekivan, budući da RAID 10 već ima dovoljnu propusnost za čitanje/pisanje za obradu mrežnog prometa, čak i s dvije agregirane veze od 1Gbps. SSD predmemorija nema stvarnu prednost u ovom scenariju (uzastopni prijenosi, s velikim, susjednim datotekama). Samo kada radno opterećenje uključuje male datoteke, SSD predmemorija čini razliku.

The specs of the hard disks or/and SSDs that you install inside the NAS will have the most impact on performance, but if you go with high-speed drives and configurations, you might hit the limitation of the network infrastructure. It all comes down to the predicted workload: make sure you design your solution based on your needs.

Unboxing the Synology DiskStation DS1621+

The DiskStation DS1621+ comes in a simple, relatively small cardboard box, but that makes sense since the device itself is very compact.

On the front, there is a sticker outlining the main advantages of the DiskStation DS1621+ and a picture of the device, while on the back you have more technical details printed on the box.

The packaging for Synology DiskStation DS1621+

Inside the package, you find the DiskStation DS1621+, a power adapter, two high-quality LAN cables, two plastic keys to lock the drive trays, a pack of screws (for mounting 2.5-inch storage drives in the 3.5-inch drive bays), and a quick installation guide.

The accessories that come with the DS1621+

The traditional approach of Synology towards packaging shows that their devices are oriented towards prosumers and professionals. There are no bells and whistles, but the package includes all the accessories needed to get the DiskStation DS1621+ going.

Hardware specifications and design

The DiskStation DS1621+ is compact, with a height of 6.53 inches (166 mm), a width of 11.1 inches (282 mm), and a depth of 9.57 inches (243 mm). At 11.2lbs (or 5.1 kg), it’s relatively heavy even without drives.

The front of the Synology DS1621+

The device has six 3.5-inch drive bays, which can be individually locked with the included keys. Each bay has its own status light. They support tool-less installation for 3.5-inch drives, while the included screws allow the installation of 2.5-inch drives as well. The drives can be configured in Synology Hybrid RAID (SHR), Basic, JBOD, RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, depending on the needs and the number of drives installed. Naturally, all drives are hot-swappable.

The drive bays allow tool-less installation of hard-drives

On the front of the DiskStation DS1621+, there’s a power button, a status LED, an alert LED, as well as four LEDs indicating the status of the LAN connection for each port. Hidden in the lower right corner, there is a USB 3.2 Gen 1 port.

The DS1621+ has three USB 3.2 Gen 1 ports in total, with one on the front

Moving to the back of the device, we have the AC power connector, a Kensington Security slot, two more USB 3.2 Gen 1 ports, four Gigabit network ports (with link aggregation support), and two eSATA ports. The Synology DiskStation DS1621+ also has a PCIe x8 expansion slot that can be used for installing, for example, a 10GbE network card.

The back of the Synology DS 1621+

The internals are looking good: an AMD Ryzen V1500B quad-core 2.2 GHz processor with up to 32 GB ECC DDR4 (ours came with the standard 4 GB) makes the device suitable for light virtual machines and multimedia applications. The flexibility of the DiskStation DS1621+ is further improved by the possibility of adding two M.2 2280 NVMe SSDs for write caching. This greatly increases reading and writing performance and allows access for a greater number of users.

The SSDs are conveniently located in the enclosure

The RAM is easily accessible as well: you only need to undo two screws on the bottom of the device and you can replace or add memory. Careful, though, it’s ECC DDR4, so you need to look for compatible modules.

Just remove two screws to gain access to the DDR4 DIMM slots

The NAS is cooled by two 90mm fans. Unfortunately, the design of the enclosure doesn’t allow an air filter to be installed, so in dusty environments, you should make sure you clean the device regularly, as it will prolong the life of the fans. When you do need to replace the fans, they are easily accessible and can be replaced through the back.

There are no dust filters on the Synology DS1621+

The DiskStation DS1621+ has a power consumption of roughly 51W when accessing the drives and about 25W when the drives are hibernating. The noise level is low in normal operation, but if you set the fans to run at 100%, you’d better have a dedicated server room with soundproofing.

If you would like to read the complete specifications of this product, you can download the Data Sheet from this page: Download Center - DS1621+.

Overall, the design is rugged and inspires confidence in the longevity of the product. There are many connectivity options, and the drives are super easy to access and replace, thanks to the tool-less mounting design. Status LEDs ensure that you can get a good idea of the state of the DiskStation DS1621+ without accessing the interface. The focus was on efficiency when designing the device, and it shows.

Setting up and using the Synology DiskStation DS1621+

We tested the DiskStation DS1621+ with five Synology 8TB drives, which were very easy to install in the bays. We were also provided with two 400GB SSD drives that we configured for read/write caching. Once you pop in all the drives, the hardware setup is straightforward: plug the AC cable, connect the NAS to the router using the LAN cable(s), and power on the device.

The DS1621+ interface can be accessed from any browser

We then chose to use the latest DiskStation Manager operating system (DSM 7.0.1). After installing the DSM and rebooting, you can configure the login details. The setup wizard then asks whether you want to install the standard recommended packages for your NAS, or if you want to install them all. You can also skip this step and install them manually later. You are then asked whether you want to create a QuickConnect ID that you can use to remotely connect to your NAS via the internet.

Setting up the QuickConnect ID on the DS1621+

As described before, your storage drives can be configured to work in any of the Synology Hybrid RAID (SHR), Basic, JBOD, RAID 0, RAID 1, RAID 5, RAID 6, RAID 10 modes. In terms of supported file systems, you can choose between Brtfs and ext4, although you can choose from more types of file systems for external drives. Configuring the file system and the RAID was as easy as choosing from several menu options. We went with a RAID 10 configuration (four of the drives, totaling a usable space of roughly 14 TB and drive redundancy), SSD caching, and a hot spare (the fifth drive). The hot spare activates when one of the RAID drives fails, and the migration and replacement are done automatically, without the need for human intervention.

The final RAID configuration, with a hot spare and SSD caching

The latest version of the DSM operating system looks great and is well organized. The graphical user interface is user-friendly and provides all the necessary visual cues for even beginners to start working with the Synology DiskStation DS1621+.

The DSM graphical interface is practical and looks good

Synology offers a modular approach for the tools and apps. After you go through the quick setup wizard, you can use the Package Center to download and install all the tools needed to personalize and use the DiskStation DS1621+ in your particular scenario. The Package Center is basically an app store with both solutions developed by Synology and apps from verified third parties.

App Store? No, Package Center

Here are some of the things that you can do with your DiskStation DS1621+:

• Private cloud storage service - you can create your version of Dropbox or OneDrive.
• Cloud backup - you can safely backup data locally from a public cloud service (like Google Drive) using Cloud Sync.
• Multimedia server - you can set the DS1621+ to store and download pictures, music and videos, and then use it to stream your content to the devices that are part of your network.
• Video surveillance - you can use the DS1621+ to store video footage from up to 40 IP cameras and access it whenever needed. There are two free IP camera licenses included.
• Backup server - you can set DS1621+ to create backups of the PCs that are connected to the network.
• Web server - you can install Apache, PHP, and Content Management Systems like WordPress or Joomla, and host your own websites.
• Web-based collaboration platform - you can install multiple tools for building a web-based collaboration platform: a chat service, a team calendar, office productivity apps, up to 5 free mail accounts on Synology MailPlus.
• Virtual machine manager - you can run multiple Windows, Linux, or even DSM virtual machines on the DS1621+.

Other packages can help turn your NAS into a VPN server, e-mail server, and even an LDAP server.

The Synology DS1621+ has a Virtual Machine Manager module

Link aggregation is a useful feature, but does little to mitigate the 1Gbps limitation of the network adapters. Especially since the CPU and file system can handle a large number of concurrent users, if you need a NAS for multiple file transfers and you think you will be limited by the network adapter bandwidth, you can purchase a PCIe expansion card.

The support documentation is easily accessible and detailed. In the DSM Help module, you get information about its features, links to tutorials, as well as links to videos that showcase the potential of your NAS, and how to set it up.

The DSM Help documentation

If you are to use the DiskStation DS1621+ in a home setting, make sure to schedule regular maintenance that includes dusting and cleaning the device, as it has no dust filter. Also, depending on the workload, the fans can get very loud. During our tests we didn’t manage to load the powerful processor at more than 60% of its capacity, but having six drives and two SSDs in such a small enclosure can lead to high temperatures nevertheless. Speaking of temperatures, the drives never went past 98.5 degrees Fahrenheit (37 degrees Celsius) during our tests. The SSDs were just a bit hotter, at 104 degrees Fahrenheit (40 degrees Celsius).

The Synology operating system is, we believe, the most advanced and user-friendly management system for network-attached storage solutions. We had no trouble setting up the Synology DiskStation DS1621+ and, while we didn’t have enough time to test out each individual scenario, we can safely say that this NAS is a very powerful tool for small businesses and enthusiasts.

How fast is Synology DiskStation DS1621+ at transferring data?

Since, after all, it is a NAS solution, we tested the transfer rates to and from other devices on the same network. The results were predictable, given the specs of the device: using link aggregation, the transfer speed maxed out at 1032 Mbps for writing data to the DiskStation DS1621+ and 1792 Mbps for reading data. This is the best-case scenario, with SSD cache and link aggregation turned on. Without link aggregation, the values were obviously lower, as the bandwidth was limited to 1 Gbps: 916 MBps for writes, 906 Mbps for reads.

The read speeds with link aggregation are very good

When we disabled the read/write cache provided by the SSDs, there was very little difference in terms of read speed from the device.

Turning off SSD caching has little effect on sequential transfers

This result is to be expected, as RAID 10 already has enough read/write bandwidth to process the network traffic, even with two aggregated 1Gbps links. SSD caching has no real advantage in this scenario (sequential transfers, with large, contiguous files). Only when the workload includes small files, the SSD caching makes a difference.

The specs of the hard disks or/and SSDs that you install inside the NAS will have the most impact on performance, but if you go with high-speed drives and configurations, you might hit the limitation of the network infrastructure. It all comes down to the predicted workload: make sure you design your solution based on your needs.
