Hardware Upgrade

[Fastline]

Hello Guys,

Happy New Year to everyone!

I'm having currently the following hardware:

Supermicro X11SSL-CF
Intel Xeon E3-1285 v6
4x16GB ECC DDR4 2400MHz
8xSeagate 10TB HDD (connected via onboard SAS3 LSI 3008 8i)
10GbE NIC
750W PSU

I'm getting a good deal on SSDs and planning to upgrade all the HDDs to SSDs. My question is when I upgrade it to SSD, will anything bottleneck here which can affect the speed? Especially the CPU/RAM.

Thanks

As long as we're talking "speed of file services" here: nope.

(Just make sure you get propper SSDs: "server grade" with PLP.)

Why would you need PLP for data drives? For SLOG, yes, but OP didn't say anything about SLOG.

Nice!

It will be a two client simultaneously accessing the NAS via SMB.

What? Isn't that required for SLOG or Special vdev?

Yes, that's what i thought!

As no VMs will be running on this mini NAS, i don't think SLOG would be required here or beneficial for my use case. However, you guys are pro. So let me know if i need one.

Thanks again!

@danb35 Well … concerning SSDs with internal (D)RAM cache it‘s not that easy to predict at what time data is effectively and truly flushed/synced. It‘s a function of the internal controller and can‘t be controlled by the OS. And then … persuasive advertising techniques combined with „vague“ fact sheets … That‘s why I never rely on SSDs w/o PLP … be it base or special vdev.

Imagine internal garbage collection / trim interrupted by a tiny little power outage. Just while those metadata blocks got shuffled around …

Hmm. But so far i was only aware that one needs that kind of drive for data vdevs as well. xD

BTW, with 8x1TB/2TB or 10x1TB/2TB SATA SSDs (500MB/s approx) what speed can be expected? disregarding the SMB limitations here? Let's say if i put 25GbE here and two clients which have 10GbE, can it work fine or i would need to add more drives to gain that kind of speed?

There are several grades of PLP, but I am not knowledgable enough to write about them. Buy an UPS and you should be good.

Sounds good!
