10GB network + perf questions etc
August 13, 2007 04:45PM
Hi Group,

Just curious to know if anyone is using 10GB network (fibre/copper, is
copper available yet at 10GB ???) on their media servers or clients and what
sort of data transfer rates are they getting ???

I'm waiting for my 10GB blade for the switch to come from the US, it's
taking ages !!!!

Also, are you using Solaris or windows on these ???

What's the best you've seen on 100MB and 1GB copper/fibre networks ???

What data rates are you seeing via HBAs 2/4GB ????

Are you using standard backup method or flashbackup ?

I've played around with flash and on a server with about 4.7TB of small
files, I have gone from 10MB/s -> 70MB/s. It's a V490

Thanks in advance,

Dominik

I think feeding the pipe is the hardest problem and 10GBps performance is
typically rated at 200-250 MiB/s in practice, at least from what I have
seen.

Copper is available. It just depends on what your network guys are comfortable with in their environment.
If you are capable of filling the pipe you can get about 8.2Gbps. Filling the pipe requires higher levels of multiplexing and lots of source points or multiple jobs.

10GB network + perf questions etc
August 23, 2007 10:46PM
Check out my blog entry on this topic:
http://www.backupcentral.com/content/view/133/47/

I just spent some time today with some REALLY smart folks who were using
Intel's 10 GbE NICs with Sun 6900s and Solaris 10. They can do about
250 MB/s and have the box still function. They can get it up to 400
MB/s, but when they do that, the box won't respond. They couldn't run
top, they can't login, they can't run ps, etc -- NOTHING.

So I'm thinking that with Solaris, you're not going to get anywhere near
10,000 Mb/s (1200 MB/s). Maybe with Linux or Windows and a TOE (TCP
offload engine) NIC, you might have a chance. (I only say those OSs
because that's where they're making TOE NICs.) One vendor replied to my
blog post and I'm looking into it.

If it's the card I'm thinking about the TCP checksum is already offload
to hardware. In fact most gigaswift cards support this today with 1 Gbit
technology.

I think a great deal of tuning would be required to achieve anywhere
near 10 GB w/ a single TCP stream.

10GB network + perf questions etc
August 24, 2007 12:26PM
On one of our media servers, I can receive 250 MB/s into my 6850 with
4 GigE connections bonded into two LACP bonds, stream that out to six
fc LTO-3 tape drives, and the box is plenty usable. We are upgrading
our network here, and I'd be surprised if I couldn't get closer to
300-350MB/s in the future. The E6900 is still PCI-X, correct? PCI-e
is a must to do anything that I/O intensive, or so I would think.
But, I'm probably not as smart as those Sun d00ds.

Yes, many times. This was a huge exposure for us at the time. The issue
was that we couldn't run a consistency check on our own, mainly due to
the size of our catalog. We were relegated, as you are, to sending
Symantec dumps of the catalog/databases, opening up a case and waiting
for them to produce a report.

The critical problem with that, is that by the time we actually got the
report and acted on it, the next backup run was in flight, making the
report largely obsolete because the catalog/databases were now being
written to again. Typically, it took a few days to clear up our
inconsistencies. Also, typically, we ran this bi-weekly to keep this
problem in check.

This has been a serious issue with NBU for years. Because the
possibility exists, as you have found out, that NBU could mark media
with live images on it as scratch media, customers are always subject
to losing data. Symantec knows this.

At least in our environment, we, nor Symantec we never able to
determine what we could do to keep these inconsistencies from occurring
in the first place.

At the time, the utility that Symantec used to determine
inconsistencies was kept from customers. It was/is called NBCC. My
understanding is that it may be available to end users now, but for a
long time, customers were, in essence, unable to help themselves in
this regard.

So, yes, I am suggesting that inherently, NBU *is* subject to data
loss, silently and at any time, due to the fact that their
catalog/databases cannot remain consistent.

Hi all,
We have been having issues with our catalog (running NBU 6.0 MP4) and
have
found that our catalog is very inconsistent. We have been running a
utility from Symantec called consistency_gather.pl, which basically
grabs
image, media and vol DB information. We send that through to Symantec
to
produce a report, which we receive back.
We have two NetBackup 6.0 environment, and both are reporting that we
have
inconsistencies in our catalog.
Has anyone else run this utility and obtained a report from Symantec.
In one of our report, it stats that of the 375000 images that we have,
about 4700 of them could be lost due to being overwritten. We also have

multiple tapes that appear to be assigned to multiple media servers,
and
the list goes on.
Anyone else run into this type of issue?

Ian.

In windows you can run this command.

"C:Program FilesVERITASnetbackupbinbpdbm" -consistency
[quote][quote]f:catalog.consistency.txt
[/quote][/quote]
On a *nix machine it should still be the same command

While it checks the catalog it will move corrupt entries to
C:Program FilesVERITASnetbackupdb.corrupt and your catalog backups
will complete. Using this command to do the consistency check and fix
it does not delete the corrupt entries so if a fix for the corrupt
entries ever happen you still have them. On our catalog it takes
approxamately 2 hours to run. Our catalog is 60+ gigs.

Should be fine the master is just telling the clients/media servers what
to do and where to send the data. As long as you have no tape drives
attached to it-- however, if you backup millions of files those files will
be written to in the catalog on the master.

This took way too long (over 24 hours) in our environment. It was never
an option for us, unfortunately.

Hi all,

We have been having issues with our catalog (running NBU 6.0 MP4) and
have found that our catalog is very inconsistent. We have been running a
utility from Symantec called consistency_gather.pl, which basically
grabs image, media and vol DB information. We send that through to
Symantec to produce a report, which we receive back.

We have two NetBackup 6.0 environment, and both are reporting that we
have inconsistencies in our catalog.

Has anyone else run this utility and obtained a report from Symantec.

In one of our report, it stats that of the 375000 images that we have,
about 4700 of them could be lost due to being overwritten. We also have
multiple tapes that appear to be assigned to multiple media servers, and
the list goes on.

Anyone else run into this type of issue?

Ian.

You may find many inconsistancies , try to resolve only

1. Media inconsistancies
a : media assign time and allocated time
b : media assigned to multiple media servers
c : remove all media servers which are not into existance
2. Image inconsistancies

On one of our media servers, I can receive 250 MB/s into my 6850 with
4 GigE connections bonded into two LACP bonds, stream that out to six
fc LTO-3 tape drives, and the box is plenty usable. We are upgrading
our network here, and I'd be surprised if I couldn't get closer to
300-350MB/s in the future. The E6900 is still PCI-X, correct? PCI-e
is a must to do anything that I/O intensive, or so I would think.
But, I'm probably not as smart as those Sun d00ds.

[quote]what
sort of data transfer rates are they getting ???

I'm waiting for my 10GB blade for the switch to come from the US, it's

Also, are you using Solaris or windows on these ???

What's the best you've seen on 100MB and 1GB copper/fibre networks ???

What data rates are you seeing via HBAs 2/4GB ????

Are you using standard backup method or flashbackup ?

I've played around with flash and on a server with about 4.7TB of

[quote]files, I have gone from 10MB/s -> 70MB/s. It's a V490

Thanks in advance,

I think a great deal of tuning would be required to achieve anywhere

Yes, many times. This was a huge exposure for us at the time. The
[/quote]issue
[quote]was that we couldn't run a consistency check on our own, mainly due to
the size of our catalog. We were relegated, as you are, to sending
Symantec dumps of the catalog/databases, opening up a case and waiting
for them to produce a report.

The critical problem with that, is that by the time we actually got
[/quote]the
[quote]report and acted on it, the next backup run was in flight, making the
report largely obsolete because the catalog/databases were now being
written to again. Typically, it took a few days to clear up our
inconsistencies. Also, typically, we ran this bi-weekly to keep this
problem in check.

This has been a serious issue with NBU for years. Because the
possibility exists, as you have found out, that NBU could mark media
with live images on it as scratch media, customers are always subject
to losing data. Symantec knows this.

At least in our environment, we, nor Symantec we never able to
determine what we could do to keep these inconsistencies from
[/quote]occurring
[quote]in the first place.

At the time, the utility that Symantec used to determine
inconsistencies was kept from customers. It was/is called NBCC. My
understanding is that it may be available to end users now, but for a
long time, customers were, in essence, unable to help themselves in
this regard.

So, yes, I am suggesting that inherently, NBU *is* subject to data
loss, silently and at any time, due to the fact that their
catalog/databases cannot remain consistent.

Hi all,

We have been having issues with our catalog (running NBU 6.0 MP4)
[/quote][/quote]and
[quote][quote]have found that our catalog is very inconsistent. We have been
[/quote][/quote]running a
[quote][quote]utility from Symantec called consistency_gather.pl, which basically
grabs image, media and vol DB information. We send that through to
Symantec to produce a report, which we receive back.

We have two NetBackup 6.0 environment, and both are reporting that
[/quote][/quote]we
[quote][quote]have inconsistencies in our catalog.

Has anyone else run this utility and obtained a report from
[/quote][/quote]Symantec.
[quote][quote]
In one of our report, it stats that of the 375000 images that we
[/quote][/quote]have,
[quote][quote]about 4700 of them could be lost due to being overwritten. We also
[/quote][/quote]have
[quote][quote]multiple tapes that appear to be assigned to multiple media servers,

[quote][quote]the list goes on.

You may find many inconsistancies , try to resolve only

1. Media inconsistancies
a : media assign time and allocated time
b : media assigned to multiple media servers
c : remove all media servers which are not into existance
2. Image inconsistancies

On one of our media servers, I can receive 250 MB/s into my 6850 with
4 GigE connections bonded into two LACP bonds, stream that out to six
fc LTO-3 tape drives, and the box is plenty usable. We are upgrading
our network here, and I'd be surprised if I couldn't get closer to
300-350MB/s in the future. The E6900 is still PCI-X, correct? PCI-e
is a must to do anything that I/O intensive, or so I would think.
But, I'm probably not as smart as those Sun d00ds.

I just spent some time today with some REALLY smart folks who were
[/quote]using
[quote]Intel's 10 GbE NICs with Sun 6900s and Solaris 10. They can do about

top, they can't login, they can't run ps, etc -- NOTHING.

So I'm thinking that with Solaris, you're not going to get anywhere
[/quote]near
[quote]10,000 Mb/s (1200 MB/s). Maybe with Linux or Windows and a TOE (TCP

Hi Group,

Just curious to know if anyone is using 10GB network (fibre/copper, is
copper available yet at 10GB ???) on their media servers or clients
[/quote]and
[quote]what
sort of data transfer rates are they getting ???

I'm waiting for my 10GB blade for the switch to come from the US, it's
taking ages !!!!

Also, are you using Solaris or windows on these ???

What's the best you've seen on 100MB and 1GB copper/fibre networks ???

What data rates are you seeing via HBAs 2/4GB ????

Are you using standard backup method or flashbackup ?

I've played around with flash and on a server with about 4.7TB of
[/quote]small
[quote]files, I have gone from 10MB/s -> 70MB/s. It's a V490

Thanks in advance,

I think a great deal of tuning would be required to achieve anywhere

Yes, many times. This was a huge exposure for us at the time. The
[/quote]issue
[quote]was that we couldn't run a consistency check on our own, mainly due to
the size of our catalog. We were relegated, as you are, to sending
Symantec dumps of the catalog/databases, opening up a case and waiting
for them to produce a report.

The critical problem with that, is that by the time we actually got
[/quote]the
[quote]report and acted on it, the next backup run was in flight, making the
report largely obsolete because the catalog/databases were now being
written to again. Typically, it took a few days to clear up our
inconsistencies. Also, typically, we ran this bi-weekly to keep this
problem in check.

This has been a serious issue with NBU for years. Because the
possibility exists, as you have found out, that NBU could mark media
with live images on it as scratch media, customers are always subject
to losing data. Symantec knows this.

At least in our environment, we, nor Symantec we never able to
determine what we could do to keep these inconsistencies from
[/quote]occurring
[quote]in the first place.

At the time, the utility that Symantec used to determine
inconsistencies was kept from customers. It was/is called NBCC. My
understanding is that it may be available to end users now, but for a
long time, customers were, in essence, unable to help themselves in
this regard.

So, yes, I am suggesting that inherently, NBU *is* subject to data
loss, silently and at any time, due to the fact that their
catalog/databases cannot remain consistent.

On a *nix machine it should still be the same command

While it checks the catalog it will move corrupt entries to

This took way too long (over 24 hours) in our environment. It was
[/quote]never
[quote]an option for us, unfortunately.

On a *nix machine it should still be the same command

While it checks the catalog it will move corrupt entries to
C:Program FilesVERITASnetbackupdb.corrupt and your catalog
[/quote][/quote]backups
[quote][quote]will complete. Using this command to do the consistency check and

[quote][quote]it does not delete the corrupt entries so if a fix for the corrupt
entries ever happen you still have them. On our catalog it takes
approxamately 2 hours to run. Our catalog is 60+ gigs.

recently?

Hi all,

We have been having issues with our catalog (running NBU 6.0 MP4)
[/quote][/quote]and
[quote][quote]have found that our catalog is very inconsistent. We have been
[/quote][/quote]running a
[quote][quote]utility from Symantec called consistency_gather.pl, which basically
grabs image, media and vol DB information. We send that through to
Symantec to produce a report, which we receive back.

We have two NetBackup 6.0 environment, and both are reporting that
[/quote][/quote]we
[quote][quote]have inconsistencies in our catalog.

Has anyone else run this utility and obtained a report from
[/quote][/quote]Symantec.
[quote][quote]
In one of our report, it stats that of the 375000 images that we
[/quote][/quote]have,
[quote][quote]about 4700 of them could be lost due to being overwritten. We also
[/quote][/quote]have
[quote][quote]multiple tapes that appear to be assigned to multiple media servers,
[/quote][/quote]and
[quote][quote]the list goes on.

Anyone else run into this type of issue?

Ian.

You may find many inconsistancies , try to resolve only

1. Media inconsistancies
a : media assign time and allocated time
b : media assigned to multiple media servers
c : remove all media servers which are not into existance
2. Image inconsistancies

10GB network + perf questions etc
August 24, 2007 07:12PM
Hi

I have 3 media servers running with a 10 GbE NIC (alll running RHEL4). Two of them use a
Intel NIC, and the other uses a NC-510F (NetXen chipset). We use 3 different server models:
a Sun V40Z, a IBM x366 and a HP DL580 g4. On my opinion, Intel(or AMD)+Linux machines
have a so much better cost/performance ratio than anything from SUN (extremely expensive
for the doubtful quality of their service and products).

All of server reach a peak of around 2-2.5 Gbps (250-300 MB/s). Using iperf, we could reach
3 Gbps using NC510F; unfortunately, it seems that the 64-bit version driver is buggy,
and we&#39;re obliged to use a 32 bits OS on a machine with 16 GB of RAM (which is very bad), which,
I believe, strongly affects netbackup performance.
I do NOT recommend this NIC at all.

Hi Group,

Just curious to know if anyone is using 10GB network (fibre/copper, is
copper available yet at 10GB ???) on their media servers or clients and what
sort of data transfer rates are they getting ???

I&#39;m waiting for my 10GB blade for the switch to come from the US, it&#39;s
taking ages !!!!

Also, are you using Solaris or windows on these ???

What&#39;s the best you&#39;ve seen on 100MB and 1GB copper/fibre networks ???

What data rates are you seeing via HBAs 2/4GB ????

Are you using standard backup method or flashbackup ?

I&#39;ve played around with flash and on a server with about 4.7TB of small
files, I have gone from 10MB/s -> 70MB/s. It&#39;s a V490

Thanks in advance,

Dominik

Offloading the checksum is not the same as a full TCP offload. A "true"
TOE card offloads ALL TCP processing, not just the checksum.

[quote]I think a great deal of tuning would be required to achieve anywhere
near 10 GB w/ a single TCP stream.
[/quote]
I think you can tune your heart out and you'll never get anywhere close.
Maybe it's possible with a TOE card, but I haven't heard from anyone
yet.

I think my point is still valid then. No one seems to be going beyond
250 MB/s -- maybe 400 MB/s with extreme pain -- with "10 Gb Ethernet."
I haven't heard from anyone doing a full TOE card, though.

Then I'd like to know how they optimized their cards :)

In 2006 we built a newbackup system using 10Gbps...

We've been getting over 3Gbs using RHEAS4/Netbackup 6 and Chelsio 10Gbit card through 1 V40z media server (we have 6 media servers in total). We are maxing our the FC to the tape library, so if we switch to 4Gbps FC cards to the tape library our might result in higher...

We initially tested the Intel/Sun 10Gbps cards and was only able to get 1Gb/s through it using ttcp testing tools. We returned the Intel/Sun 10Gb cards... Intel has dual 10Gbps nics now, but we have not tested them.

We were able to get over 7Gbps on the Chelsio card using ttcp between two media V40z and a cisco switch
