Fantastic build quality and physical design


Cons

 Lacks 10GbE


LACP switch adds to the cost



Aimed at both enterprise and house users in having to have of gigantic amounts of storage, the DS1815+ is definitely an eight-bay NAS from Synology, powered by a quad-core CPU and as much as 6GB of memory. This areas it at the really opposite finish of the functionality scale from the single-bay DS115J that came out late final year.

 

Having a retail expense of about £850 (US$1030, AU$132) it is in the upper finish of NAS pricing, despite the fact that 1 step beneath the level occupied by rack-mount NAS units, which include the Thecus NN810U-G or Synology's 12-bay RackStation RS3614xs+.

 

You'll find 4 USB three ports at the back in conjunction with the two eSATA ports, a pair of massive fans and an internal energy supply, so a standard "kettle" lead is all you may need to obtain it up and running.

 

The DS1815+ is powered by a quad-core Intel Atom C2358 processor, which runs at2.4GHz, a chip which need to be sufficient to cope with several users simultaneously. You'll find two memory slots, a single occupied by a 2GB DDR3 SODIMM as common.

 

Due to the fact plastic can break, I believed it an excellent concept to look at the best way to replace a broken mounting bracket if the have to have arose. Synology lists plenty of spare components on its site, but you can't order them straight. Instead, the firm says to find a reseller, who ought to be in a position to help.

 

The trump card of all Synology's NASsolutions is DiskStation Manager, the great Linux-based operating program that powers them. It delivers a familiar Windows-like atmosphere, accessible via a browser, with groups of icons and menus to navigate around the technique and widgets to supply at-a-glance information and facts, such as internal temperature, CPU utilisation, and so on.

 

Testing and setup

 

I filled the DS1815+ with eight WD Red 6TBchallenging disks, set up to utilize Synology Hybrid RAID. The create procedure completed in around 30 minutes, and following the software was updated I was ready to find out what speeds I could get from it.

 

Early on, I ran into what I consider to be a significant overall performance problem, which applies to numerous NAS devices with multiple gigabit ethernet ports. Even though the DS1815+ enables its four gigabit ethernet ports to become bonded together and applied to a single connection, in order to get four instances the usual gigabit speed when performing a single file transfer, your network switch ought to support both 802.3ad hyperlink aggregation and LACP, or dynamic link aggregation. Most modern days managed switches support 802.3ad, but not all help LACP, as I discovered.

 

When the DS1815+ is very first powered on, each port is assigned a separate IP address. When they are bonded collectively inside the DiskStation Manager application, the unit only wants a single address, but you are going to only get regular gigabit speeds through any single transfer. There is still an overall performance benefit though, mainly because with up to four consumers transferring files at the same time, the DS1815+ can deliver a complete 1Gbit/sec to each client.

 

For the complete 4Gbit/sec speed from a single transfer, you will need to adjust the configuration of your switch to bond these parts together into a LAG group. Unmanaged cheap desktop switches never even have any configuration computer software, so you'll need to look at a managed switch. Whilst frequent in modest company environments, they're hardly a crucial property networking buy, and this feature is not exactly typical on routers either.

 

I tested the capabilities of your DS1815+ working with Intel's NAS performance toolkit plus a regular Windows file transfer of 5GB folders of each large and modest files. I could only test the complete speed working with a file transfer though, given that my time together with the HP ProCurve switch was limited.

 

At standard gigabit speeds, the DS1815+ is a leap ahead of its predecessor and shows great functionality in tiny file transfers, particularly in tests that put strain on the CPU.
