Enterprise-level powerhouse in the home!
TS-h886 is damn good!
A NAS serve me two significant purposes: to secure my work data and centralise all the data to allow us access from all devices.
We start by installing a single Samsung 860 EVO 1TB 2.5" SSD as system disk for QNAP application. During the initial setup, we swap the OS install from the enterprise-grade QuTS Hero to a more prosumer QTS. The reason behind this approach is after an in-depth comparison from the QNAP official documents and discussion with the QNAP officer twice. However, the ZFS system from QuTS Hero can provide unbeatable performance and crazy 65535 snapshot capability. We choose to use the EXT4 based QTS system which can supports change of RAID type and the capacity of adding new drive into the existing RAID.
TS-h886 comes with 8 disk slot in total
NVMe#1: Samsung NVMe SSD 256GB for read/write caching
NVMe#2: Samsung NVMe SSD 256GB for read/write caching
SSD#1: Samsung 860 EVO 2.5" SATA SSD (1TB) for System and QNAP Application (Storage Pool 1 — Basic)
HDD#1: WD HGST Helium 8TB for Main Data (Storage Pool 2 — RAID1)
HDD#2: WD HGST Helium 8TB for Main Data (Storage Pool 2 — RAID1)
HDD#3: Reserved for Storage Pool 2 Expansion to RAID 5
HDD#4: WD NAS Red PMR 5TB for testbed data(Storage Pool 3 — Basic)
HDD#5: Reserved for Storage Pool 4 Expansion to RAID 1
HDD#6: Seagate SMR 8TB for Archive Data (Storage Pool 4 — Basic)
The Xeon D-1622 CPU in TS-h886 is a low power consumption CPU, give us a slightly lower performance score from TVS-872XT with a six cores i5–8500T CPU. While it is a Xeon CPU, it does not have GPU rendering natively, and luckily we don’t quite need to transcode video in this setup. It also does not have HDMI output, different from the other QNAP offer. By adopting the Xeon Family CPU, the TS-h886 and the TS-h686 series provided a generous 32 PCI-E Lane in total.
PCIe Lanes Allocation
Xeon D-1622 comes with 24 Lanes PCIe 3.0 and 8 Lanes PCIe 2.0 as follow:
INTEL Xeon (R) D-1622
—PCIe 3.0 x 24
| + — PCIe 3.0 x 4 : NVMe Slot 1 — SAMSUNG NVMe SSD
| + — PCIe 3.0 x 4 : NVMe Slot 2 — SAMSUNG NVMe SSD
| + — PCIe 3.0 x 8 : PCIe Slot 1
| + — PCIe 3.0 x 8 : PCIe Slot 2 (Low Profile)
— PCIe 2.0 x 8
| + — PCIe 2.0 x 4
—| + — PCIe 2.0 x 1 : RTL8125 2.5GBE ETHERNET 1
— | + — PCIe 2.0 x 1 : RTL8125 2.5GBE ETHERNET 2
— | + — PCIe 2.0 x 1 : RTL8125 2.5GBE ETHERNET 3
— | + — PCIe 2.0 x 1 : RTL8125 2.5GBE ETHERNET 4
| + — PCIe 2.0 x 2 : Asmedia 106x SATA/RAID Controller
— |+ — PCIe 2.0 x 1 : 3.5" SATA 3.0 6Gbps (Bay 5)
— |+ — PCIe 2.0 x 1 : 3.5" SATA 3.0 6Gbps (Bay 6)
| + — PCIe 2.0 x 2 : Not in use
Note that the HDD Bay 5 and 6 are sharing PCIe 2.0 x 2 Lanes, which equivalent to 1000MB/s in total. Prevent to use these two bay for SSD.
TS-h886 provided excellent expandability to his user. I am planning to upgrade the RAM to 128GB (32x4) in the coming weeks and seek for some funny experiments the TS-h886 can do.
