QNAP x82 strong enough for Plex and Virtualstation?

[aarbee]

Saying that I put in the 2 M2's, would I benefit more from adding the extra 2 SSD's, then say add 4*4TB disks for all? And Raid 5.

Thanks for your insight. This is a bit undiscovered country for me.

So assuming the m.2's are for caching only, it really depends on what you need most ... storage or performance.

I get magnitudes faster performance from my m.2 SSD vs. my 6-drive RAID-5 (@7200RPM).

If you go with the smaller 4-drive chassis, that does limit your flexibility as RAID-5 needs at least 3 drives, and RAID-1 is 2. So you either get (1) Raid-5 config, or (2) Raid-1 options in a 473.

The 673 would give you more flexibility in that regard, and I think it is about $50-100 more vs. the 473 (amazon US pricing). You could have a 4-drive raid-5 + a 2-drive Raid-1 on top of your m.2 caching.

Well No diapers for your baby then . Sorry hehe.
The price difference here (Netherlands) is rather big.
€ 1014 for the 473 and € 1153 for the 673 Hardly available except if I wait a week. Else it is over 1200 if I want it within 24 hours.
I can wait. Looking for half a year by now. So what is 5 days more?
Somehow you convinced of the bigger box. Second time by the way.

In that case I could go for the cheaper 3TB. Speed is about the same as the 4TB.
Only the 5 and 6 TB are faster.Not sure what to do with 18TB. Except for filling up.

Then just start with pulling nr 2 out of my 239 and insert it in the new box.
(have planned a complete reorganisation of my data. I guess it is better this way.)
Ah yeah and use the external disk for a complete extra backup. Internet backup/restore is slow. Even on a 30mbit upload.

Thanks for your time.
Will let you know, when I order it, and what.

[Trexx]

Also make sure and get a good UPS for it... RAID won't protect against data loss due to power glitch.

[aarbee]

Took the UPS out of my system. few years ago. Not sure about the effect. Had to rebuild the raid anyway after an poweroutage.
I think I have an APC Back UPS RS500 or 450. Did run about 10-15 minutes. And the machine stopped after an outage. There is mostly an outage when I am not at home. The rest of the family does not know what to do about the computerroom switch .

Any advice?

[aarbee]

Ordered 673 @ 8GB and 1 4TB HGST nas disk. (Going to add the existing ones in time.)
I think I'll put a new battery in my old UPS and lets see if it functions.

[aarbee]

My UPS is a CS500. And all batteries, including the spare that I had, show a read light. Replace battery. Wonder what that would mean .
To be honest, I had not expect that a never been used battery would not work in here.
The milliondollar question is buy a new battery for this device, or buy a newer model?
To my knowledge, this device did not run longer then 10 minutes on my back then present server, and dropped out, without proper switching off. Perhaps did not understood the volt*ampere not. Considered 500va as 500volt-ampere = 500 watt.
If a server uses 100 watt per hour it should run 5 hours on it, not 10 minutes.

10 minutes is quite normal at full-load.

Ah, no.

500W indicates the maximum load the UPS can power-protect - it does not indicate the time for which the UPS will support that load. But the backup time for a fairly standard UPS should be around 10 minutes.

10 minutes at full-load (I'm ignoring power-factor and inductive-loads to keep it simple), means that if you only had a 100W load, you would extend that time to 50 minutes.

To get more time than that, you need to add more (or larger) batteries.

[aarbee]

Thanks for the explanation. I always thought that 500watt was, what was stored in the battery.
No wonder, the ups dropped out after 10 minutes. Until now the only explanation I understood.

Is it wise to buy a new device, because this device is from somewhere 2004/2005?

[P3R]

I had not expect that a never been used battery would not work in here.

Batteries normally doesn't age well unused and especially the lead/acid-batteries normally used in a UPS need to be excercised by regularl charges as they have a high self-discharge rate. If not they will quickly deteriorate considerably.

The milliondollar question is buy a new battery for this device, or buy a newer model?

You could try to connect the USB signal cable between the UPS and the NAS, configure the NAS accordingly and see if they communicate reliably (I assume here they should be able to establish a valid communication despite the UPS batteries are being depleted). If that test was successful you could compare the replacement battery cost with a new UPS (taking into consideration also the warranty of the new UPS).

The UPS you have is a low end model but when looking at battery replacement prices, I would probably try a new battery if the UPS communicates properly with the NAS.

To my knowledge, this device did not run longer then 10 minutes on my back then present server, and dropped out, without proper switching off.

For a controlled server/computer shutdown to occur you need a separate signal cable connected and a compatible software configured on the protected system with a large enough time margin to actually power down the NAS.

Considered 500va as 500volt-ampere = 500 watt.

Not correct.

If a server uses 100 watt per hour it should run 5 hours on it, not 10 minutes.

If a server uses 100.5 W it should run 23.8 minutes on that UPS according to the specifications. That would however assume optimal conditions and an absolutely fresh battery. With a slightly higher load (many servers consume more than 100 W) and anything less than a new battery, expect much shorter times. Also that of course requires the server/computer to be the only device being power from the UPS (usually most of us also connect a router and/or a switch to the UPS).

[aarbee]

Thanks P3R.

I think that the battery is completely depleted. As I have bought that spare one 5 maybe 6 years ago.
The light is red on the moment. And beeps constantly.
Qnap says it is Normal and at 0%.

That one was not the cheapest. But indeed not belonging to the more expensive ones.

TVS-673 has arrived.
I am a bit struggling with setting it up.
I had expected see a spot where to setup raid 1 (added 2 disks.)
I only see storage pools and volumes (thick and thin.)

Do you really need to start with the Storagepools? Eventhough I only want Raid 1, and later Raid 5?

[Trexx]

Yes start with storage pools (thick). It will then after that get to raid setup. Set snapshot amount % can be changed after initial setup. Volume size can be expanded but not shrunk after initial setup.

Also make sure you select your HDD's (and NOT m.2's) when setting up your initial storage pool.

This tutorial may help make things clearer:

Understood more or the less.
Installed 2 2.5" 320GB disks and uploaded some movies.
Is this the proper share from the Nas to pick it up? /share/CACHEDEV1_DATA
It looks like it is taking it from a cache disk?

That is just what Qnap names the 1st storage pool. Has nothing to do with the ssd cache.
