FAS2020, only 30MB/s throughput and the Tech Support says it's normal????

I am very unable with my $35000 FAS2020 purchase.  Unfortunately, I bought two of them.They are populated with 12 1TB Seagate ES.2 7200K drives.

I only getting 30MB/s throughput from it, everyone in my company is complaining about it performance.  And the NetApp Tech support  says it's normal!!!??

Even my single disk Seagate Barracula.12 (100MB/s Read) is faster than it.

Man!!!

Re: FAS2020, only 30MB/s throughput and the Tech Support says it's normal????

The FAS2020 isn't a speed demon but we get 50MB/sec from ours over NFS, and that's without doing any kind of tuning or using jumbo frames.

It's really impossible to diagnose speed problems without information on your network configuration, drivers, OS, network card types, or indeed what sort of test you're doing to measure the speed.

Re: FAS2020, only 30MB/s throughput and the Tech Support says it's normal????

I read the post, and as can i undestand, your report a data throughput in "????" only at 30MB/s using a FAS2020....

I can say also that this it is normal if for example some other applications running....

If you not clarify the problem, noone can help you resolving with performance issues.. or simple understand what the problem is...

Is this a filer performance, problem with a database on SQL Server or Oracle?

A problem with CIFS, NFS or FCP?

You also said that Tech Support says that this is normal...

Did you open any technical case? If yes, paste the content of the case,  to better understand your problem in depth....

Re: FAS2020, only 30MB/s throughput and the Tech Support says it's normal????

Good points here.  The key question comes down to what is the performance requirement and was there a sizing analysis prior to the system being quoted?  Due diligence to size the solution, even when entry level on a 2020 is important.  NetApp has very good sizing tools that take all workloads (sequential, random, read%, write%, working set size) and the ability to combine workloads of different types to make sure the right controller and number of spindles are quoted.  Often we are able to troubleshoot network configuration (flow control, lacp misconfigured, crc errors on the switch, etc) or other issues when we know the system was sized properly.

To say 30MB/sec is normal isn't a good answer from support... it may or may not be depending on your spindle type, spindle count and workloads.  2020s often push 100MB/sec read and 50MB/sec write from some of the systems I have looked at in production, but that can vary by many factors already mentioned.

Re: FAS2020, only 30MB/s throughput and the Tech Support says it's normal????

Well, there are a few differences to your laptop drive... or wherever the Barracuda is...

1) It isn't part of a raid set where parity has to be calculated and written

2) If the Barracuda fails, you get to find a compatible drive, unscrew your system, insert the new drive, install an OS, restore the rest. Even on a raid system, you get to rebuild the array manually, often enough.

3) The Barracuda is probably doing simple single file operations, where your NetApp is doing a lot more searching for multiple I/O operations

4) The Barracuda is simply responding to I/O instructions from its upper I/O stack.  The NetApp is pushing data over the semi-broken SMB 1.0 stack (I'm assuming you haven't gotten to SMB 2.0 yet)

NetApp produces Enterprise class storage systems that can do a lot of almost magical things.  They don't sell "disk".  If your only concern was $/GB, then a box of 4TB usb disks might have been a better idea.

You probably could get more out of your systems, but I think I'll leave that exercise for you.  Choosing SATA drives and then complaining about performance would seem to point to a poor pre-sales investigation.

Re: FAS2020, only 30MB/s throughput and the Tech Support says it's normal????

You are right.  So here's the info of our setup

network configuration,


I am using dual multi-path 4Gb/s Fiber connections from my FAS2020 to my Windows 2008 Std R2 64bit server box with 2 F/O HBA support up to 10Gb/s.  I created a lun on the aggr and with GPT format for my Windows environment.

This is what it looks like in my SAN, vol0 for the OnTap OS, vol1 for my VMware via NFS, Lun1 for storage on my 2008 server.

Space allocated to volumes in the aggregate
Volume                          Allocated            Used       Guarantee

drivers,

You mean the onTAP?  7.2.3. 

HBA driver, the latest version


OS,

onTAP?  7.2.3.

Windows 2008 Std R2 64bit


network card types,

Not related, but it's the onboard BroadComm 1Gbit network card x 4


what sort of test you're doing to measure the speed.

I am using HD Tune Pro, HdTach, Atto Disk Bench, PassMark (all newest version) running from my win 2008 server host.  All benchmark I performed all consistant.  around 30MB/s

From my other SAN, a Xraytex 6GB 12 x 500GB, same setup.  200MB/s!!!!!!!!!!!

Re: FAS2020, only 30MB/s throughput and the Tech Support says it's normal????

your report a data throughput in "????" only at 30MB/s using a FAS2020....

???? = accessing the filer's lun via FCP from my windows 2008 server R2 64bit.  Mounted as a GPT drive.

Please note that I am talking about sequential access here!  I expect way better performance from a $35K filer.  I use the filer to keep my company systems images backup.  All files are larger than 50GB.

here's the response from the case owner:

I have reviewed the perfstats  you have submitted and don’t see any performance related issues occurring. The  filer is performing NFS operations exclusively, the CPU doesn’t exceed 5% usage  in any of the perfstat data submitted, the disks are not overly taxed with any  workload.


Like we had discussed  previously, you are only able to work with the disks available (12 total, 10 in  RAID and 2 spares) and you would probably benefit greatly from added disks. In  addition, the disks you are using are 7200K SATA. These are low performance disks typically deployed for  non-iop intensive data like logs (sequential read data) or user home  directories. It is typically recommended that 15K FC/SAS drives or greater be  deployed for VM’s and random-read type databases like  Exchange.

I am not sure if I am suppose to post his name.

But I strongly disagree with him, 7200K SATA might not be fast as the 15K FC/SAS but they are nowhere in the 30MB/s range.  The SATA disk used by NetAPP are low-end enterprise drives according to the spec I got from Seagate website, but their speed should be way higher than 30MB/s.  So it's the problem is the performance of the filer.

Re: FAS2020, only 30MB/s throughput and the Tech Support says it's normal????

I would accept the filer if the performance is 100MB/s read and 50MB/s write, even tho I am getting 200MB/s read and write from my other SAN with 12 x 500GB SATA 7200rpm I got for the same price as the FAS2020 and it is even 4 years older than the FAS2020.

Re: FAS2020, only 30MB/s throughput and the Tech Support says it's normal????

Shaun,

I have been playing around with RAID storage for the last 15 years.  So I just going to ignor your 4 point statement.

As a world-wide company, I had the chance to purchase other different enterprise class storage systems and know what to expect from them with the price we pay.

You got that right NetApp doesn't sell "disk."  As in my earlier replies. We also have a Xraytex 5604 SAN populated with 12 X 500GB (6TB in total)  I am getting 5TB of usable space. 

From my FAS2020, 12 x 1TB (12TB in total)  I am getting less than 6TB of usable space.

Xraytex: 6 years, 24/7 usage, 1 disk failed, but no downtime, RAID60, 1 hot spare, never need servicing.

FAS2020: 2 years, 1% of usage, no disk failed, RAID-DP, 2 hot spare. Snapmirror failed after 6 months by itself, LUN goes offline when it's filled, hung our server (had to disconnect the filer to get my server start up properly), NetApp Tech still can't get it fixed, downtime for the production.  This is what you call magic?

I admit it was a poor pre-sales investigation that I trust that sale guy who also got us the Xraytex.  We have black-listed him for any future company purchase.

Re: FAS2020, only 30MB/s throughput and the Tech Support says it's normal????

Hi

could you send the outputs from the following commands:

lun show -v

igroup show -v

ifstat -a

Did you create the lun from NetApp command line interface or filerview? or from Windows using SnapDrive?

Whats your allocation status for this lun? run the following command to get a status for fragmentation level

reallocate measure /vol/volname/qtree/lunname.lun

also from Windows w2k8 run msinfo32.exe and send me the output

thanks

Re: FAS2020, only 30MB/s throughput and the Tech Support says it's normal????

  • In Windows, click Start > Run > then enter msinfo32.exe to run System Information.
  • Select Components > Storage > Disks, scroll to the bottom and you will see the Partition Starting Offset information.

What this number is?

When using Windows 2008 and any version of DOT 7.2.5 and above


Lun type 'windows_2008' is available


windows_2008 lun type supports the new geometry that Microsoft uses in Windows 2008 server


Default settings can be used when creating partitions, either through the CLI or the MMC

The lun will be aligned to a 4K boundary and will not result in performance degradation.

Note: Windows 2008 Server defaults for partition starting offset alignment are:

LUNs less than 4GB in size will align to 64KB
LUNs larger than 4GB will align to 1MB

Re: FAS2020, only 30MB/s throughput and the Tech Support says it's normal????

Hi there,

First off, I want to thank you for looking at my problem.   I created the lun from either FileView or NetApp System Manager (I can't remember it's 2 years ago.)

Here's the info you asked, see attachment

DELSNBKUP001> reallocate measure /vol/lun1/lun1

Reallocation scan will be started on '/vol/lun1/lun1'.

Monitor the system log for results.

This didn't give me any output I assume it's in the log somewhere?

Re: FAS2020, only 30MB/s throughput and the Tech Support says it's normal????

First

From a quick review on your ethernet stats it seems that
Bus overruns is more than 5% of the total number of frames in an interval and this is a performance issue (Open a new technical case and report for this error)


also you have set flow control to "none"

What type/vendor/model of ethernet switch do you have?


Second

go to msinfo32.exe on your Windows Machine

In Windows, click Start > Run > then enter msinfo32.exe to run System Information.

Select Components > Storage > Disks, find your LUN!

scroll to the bottom and you will see the Partition Starting Offset information.

What this number is?

I think there is also an alignment issue with wrong type lun selected.

LUN type must configured as windows_2008

How to troubleshoot network connectivity with Gigabit Ethernet Controller II

KB ID: 1010113 Version: 1.0 Published date: 10/11/2010

Description
Duplex

Cannot reach network

Link down

reads are fast writes are slow

No link light

reads are slow writes are fast

Cannot ping

Procedure

Confirm that the Gigabit Ethernet Controller II card is setup and configured properly.


NOTE: Manual and auto negotiation MUST be set on the attached network device (switch or peer network card), not on the filer's Gigabit card. The Gigabit Ethernet Controller II is "self-configuring" when negotiating speed and duplex. To modify network device negotiation please refer to the network device manual or contact your network administrator



  1. Execute 'sysconfig -v' to confirm the following:
    a. "NetApp Release" must be Data ONTAP 5.3.4 or greater.
    b. "Gigabit Ethernet Controller" should have "II" appended.

  2. Confirm supported network cables and connectors are used.
    a. Cables must be 1000BASE-SX (SX stands for "short wavelength")
    b. 62.5 micron multimode fiber cable with SC connectors support up to 220m distances.
    c. 50 micron multimode fiber cable with SC connectors support up to 550m distances.

  3. Confirm the Gigabit card is configured properly.
    a. To properly configure the card enter 'setup' on the filer.
    b. Entering '^c' aborts setup without committing changes to the filer.
    c. After successfully running setup it will be necessary to reboot to implement changes.
    d. Execute 'ifconfig ' to confirm that the card is "UP", and the "netmask", "broadcast" and "inet" address are correct. (Regardless of the negotiation set on the network device, the Gigabit card will always report "auto-1000sx-fd-up".)<

  4. Verify the Gigabit link has connectivity.
    a. Ensure the network cable is properly installed.
    b. Confirm that the filer link LED, physically located on the Gigabit card, is illuminated. Absence of an illuminated link LED indicates that the Gigabit card, the cable, and/or the partner network device is not working properly.
    c. Check link indicators on the attached network device ( refer to NOTE above )
    d. Verify that the switch and clients are configured properly.

  5. Determine whether the attached network device is set to manual or auto negotiation. (refer to NOTE above)
    a. If the Gigabit card cannot communicate on the network try changing the negotiation. If the switch is using auto-negotiation try changing it to manual negotiation.

  6. Turn on full flowcontrol on the filer, switch and client.
    To activate flowcontrol on the filer enter 'ifconfig ' to see if it is already set to full. If it is not, enter 'ifconfig flowcontrol full'.
    Note: To configure flowcontrol on the switch and client contact the vendor technical support.

  7. If problems persist, attach the Gigabit card to a network device port and cable that are "known good" (known to be working correctly).
    a. After attaching the interface to a known good device, toggle the interface down and up by entering 'ifconfig down' then 'ifconfig up'.
    b. Execute 'ifconfig ' to confirm that the card is "UP", and the "netmask", "broadcast" and "inet" address are correct.
    c. If this is the first attempt using the known good network equipment go to step 4 otherwise continue.
    d. If the Gigabit does not work with the known good port and cable then possibly the Gigabit card may be defective or incompatible with the network device.

I believe DOT 7.2.3 (my version) also has the options of lun type "windows_2008"

I went for GPT because I still have a few windows 2003 servers in our environment that might need to FCP to the filer and access it as lun.  (the filer is connected to a fibre switch)

However, if great performance can be achieved by switching to windows_2008 type, I will consider.  I assume it means the current lun has to be destroyed?

Re: FAS2020, only 30MB/s throughput and the Tech Support says it's normal????

That this is a production line, open a new technical case, or re-open the old case,, and provide with this information.

You need an escalation to verify all this system configuration, but from experience this configuration isn't normal. Mis-alignment on luns can lead

in performance degradation.

We have many customers with experience this kind of issues..

Also you have to update your Data Ontap to a version = or > to v7.2.7 to support interoperability with Windows 2008..

Data Ontap 7.3.5.1 is the minimum version for Windows 2008 R2 Domain Controllers and Windows Client Configuration

Your network configuration maybe is wrong on switch or storage (flow control must be full)
