QNAP CES 2017

[P3R]

i assumed since the current enterprise has zfs wouldn't this new model have that option as well ?

As far as I can tell by a quick glance on the website, only the ES-series (currently only a single model, the ES1640dc v2) use ZFS in the FreeBSD-based QES operating system. So totally different from the Linux-based QTS.

at least another item i know your able to select the filesystem in use, whether it be btrfs or the normal EXT4. does it work like that on the qnap enterprise ?

Looking at the documentation, all models from TS-128 up to all enterprise models (except the ES-series) run QTS with the file systems available there. I don't know anything else than ext4. Maybe ext3 is still supported but I don't see any point in using that over ext4.

..... oh the bugs will be rampant ... they can't even deal with what they have now ....

Ditto, nevermind launching more products, make the stuff available now work and stop adding features your support teams can't handle when asked!

Spend more time training support engineers, the quality and knowledge of some of them is appalling.

The thunderbolt models have flakey IP over thunderbolt as is.

o... so thats how their implementation works thx

Only ES1640DC v2 & TES models suppport ZFS.

[Moogle Stiltzkin]

Only ES1640DC v2 & TES models suppport ZFS.

ah hopefully we get more modern filesystem for more existing models maybe by next or late this year btrfs with dedup disabled (for those of us without much ram to meet the requirements), and not using btrfs raid 5/6 (not stable), but instead mdraid layered with a btrfs filesystem over it or zfs (assuming they can add it for units with not much ram)


By the way look familiar?

...or zfs (assuming they can add it for units with not much ram)...

ZFS is also very demanding for RAM. There are no free lunches...

the qnap booth (i don't see any booth babes ...)

Booth babes (and men) are great if they're technically competent enough to answer all questions on the products.

Hopefully also most of the audience have come out of their undeveloped early teens and therefore are more interested in the products than drooling over young females (maybe also men?) or at least have acquired the capability to separate the two interests into more appropriate separate venues.

If Qnap as yet another modern manufacturer have the courage to depend on their products to attract interest instead of having to hire young, more or less dressed, females (or males) to get attention, they have yet another huge plus in my book.

Two M.2 slots are also available for additional SATA storage, while three PCIe Gen 3 expansions slots can be used for additional networking, controllers, or NVMe SSDs.

Finally! NVMe!

and 3d xpoint is also around the corner. maybe we will see support within 1-2 years from now on a qnap perhaps

Intel Optane M.2. format card

Intel Optane memory is a new class of non-volatile memory (NVM) device which accelerates client systems to unleash the new high performance experiences users demand. By pairing either a 16GB or 32GB Intel Optane memory module (via an M.2 motherboard slot) with a large-capacity hard drive or SATA solid state drive users can get SSD-like speed while maintaining capacity and affordability. Note that they said SATA SSD or HDD as this technology isn’t meant to be paired with high-end PCIe SSDs it appears.

NVMe cards in the PCI slots were supported on some models before...

I only have experience (limited) with ONE manufacturer that is using btrfs for the file system. 12 drives, all 10 TB HGST.
A drive failed after 4 months - it took 8 days to rebuild from the RAID. If this is what btrfs has to offer in the "real world"
well that scares me.

Is this a "Btrfs-RAID" or a Btrfs as a pure file system on top of ie. mdadm RAID?

[Bob Zelin]

this is a btrfs RAID. It's from a well know company in the video industry, but I can't "name names" here. I have been dealing with RAIDs and particularly hardware raids for a long time, and I have never
seen such poor rebuilds - even from companies that I don't like. To me, if it is "acceptable" for a btrfs raid rebuild of a 120 TB array to take 8 days to rebuild (even if it is 50% full) - that is unacceptable.
Again, I am very ignorant of the btrfs file system.

btrfs raid 5 and 6 is far from stable. we were misled into believing by the dev, stable status, and then months later they found out serious issues with it....

Btrfs File-System Changes Submitted For Linux 4.10
16 December 2016

What makes the Btrfs updates for Linux 4.10 a bit less exciting is that it doesn't have a proper/full fix yet for the RAID 5/6 issue and the long-standing possible data corruption bug that is admittedly low-urgency but deals with reading a file with a hole positioned after an inline extent returning uninitalized memory when using Btrfs with zlib compression.

https://www.phoronix.com/scan.php?page= ... -56-Is-Bad
https://www.phoronix.com/scan.php?page= ... fs-Updates

some who had earlier adopted btrfs using it with regular mdadm , to avoid the issue of btrfs raid5/6 which is not ready for production use....

whether even then such a system is stable i don't know cause i don't personally have one to test myself

120 TB array to take 8 days

not sure if there is any solution to do with raid that can do better than this or does anyone know ? my particular usage atm is sitting close to 10tb of which takes around 1-3 days rebuild time from first init for setup.


anyway if you want to continue this further might want to start a new thread since were going off topic
