Reviewing the Synology DS1817+ with M2D17

Intro

The Synology DS1817+ and DS1517+ are announced in April 2017. The Synology DS1817+ is offered in both 2GB and 8GB RAM variants; and it officially supports up to 16GB. Three new accessories are also announced, namely: the (1) M2D17 dual M.2 SSD adapter; (2) DX517 5-bay expansion unit; and (3) E10G15-F1 10GbE NIC. We will be reviewing the Synology DS1817+ with the M2D17 dual M.2 SSD adapter for read-write cache.

The DS1817+ will be replacing my current Synology DS1515+. Meanwhile for this review, I will be using the Seagate IronWolf 10TB hard disks.

DS1817’s 10GbE ports

One noteworthy point is that the DS1817 has two (2) 10GbE network ports while the DS1817+ doesn’t. For the DS1817+, you can add this capability with the PCIe network adapter.

The Intel C2538 fix

One concern I had with the DS1817+ is the use of Intel C2538. Recently, devices with C2538 suffered sudden failures and required hardware fix as mitigation. Synology assured that relevant fixes or design considerations have been applied for all Synology models (utilizing C2538) since February 2017.

Avoton instead of Denverton CPU

As for the choice of Avoton over Denverton or Apollo Lake, it was mentioned that Denverton would only be released after 2017 Q2. Unfortunately, it is too late for DS1817+.

Apollo Lake is not used as it is not meant for server usage according to Intel’s classification. Perhaps future Synology models in 2018 will be using Denverton?

 

Unboxing the Synology DS1817+

The Synology DS1817+ is a 8-bay NAS announced in April 2017. It is offered in either 2GB or 8GB RAM variant.

The Synology DS1817+ package is pretty bulky and weighs around 7 kg. It is not as easy to lug around like the DS1515+ that I have now. I had totally under-estimated the strain that it would have on my arms when I carried it back on public bus. Reminder to self that I should have just take a cab for any NAS that has more than five (5) bays.

The contents of the DS1817+ package.

The DS1817+ package comes with:

  • Synology DS1817+ NAS;
  • Pack of screws for mounting 2.5″ drives;
  • Keys for securing the drive bays;
  • Installation guide;
  • Power cord; and
  • Two (2) Ethernet patch cords.

The power cord directly plugs into the power supply unit. There is no external ‘power brick’.

    i’ve been looking at upgraded NAS offerings. this seems like a great choice, my workflows are mostly IOPS limited, so this would represent a significant increase in performance and a significant decrease in keyboard smashing stress.
