Re: [Veritas-bu] hp lto3 in sun library

2007-11-16 Thread Ed Wilts
If this is a hardware based encryption product, then you probably still want
the tape drive to do compression.  Although it won't do much, typically the
ends of blocks get compressed.  For our Decru appliances, the Decru expert
we had on site said to make sure that tape drive compression stayed enabled
since there will be a nice set of zeros padding the end of the buffers that
the drive will compress away.

No other activity on the server except for the read stream from VTL and the 
write stream to LTO3.  There are a couple GB allocated for shmmem.

Depending on how many streams and write drives are running

You may see better performance by connecting the tapes and CDL to
different HBAs in different slots on separate busses.

Yes, there's more than enough "bandwidth", but the bus has to reverse
direction to send/receive, so if you have your cards laid out so one bus
is "sending" and the other "receiving" you will see better total
throughput.

Sounds good.  If you have a scratch tape and the time to do it, I'd run
a 'dd' test.

mt -f /dev/rmt/0cbn rewind
dd if=/dev/zero of=/dev/rmt/0cbn bs=256k
mt -f /dev/rmt/0cbn rewind
dd if=/dev/zero of=/dev/rmt/0hbn bs=256k

Count the number of blocks transferred and multiply by 256K to get
bytes.  The first should be several times larger than the second due to
the high compressibility of the zeros.

[Veritas-bu] poor backup speeds

2007-11-16 Thread Chris_Millet

We need more details too.  I'm guessing this is probably 420KB/sec (like what 
you would see in the job detail) which is dismal.  Even 4.2MB/sec is pretty 
bad.  42MB/sec would be OK, but I'd be guessing the bottleneck is the VM.

It sounds like you are saying you have one of the tape drives zoned directly to 
the VM and it writes directly to the drive so that data is not going over the 
network.  If so, you should see good performance.

Things to consider..
Make absolutely sure the data is being sent to the drive on the VM.  
Double-check your configs.  Have you confirmed I/O is on the VM going to the 
drive?  Maybe your accidently sending it to the master/media server still over 
the network.

Consider the VM resources.. what is it doing during the backup?  Is the CPU 
pegged, memory util at 100% or what?

Data type.. file systems with millions of tiny files tend to backup slow.  You 
could try a raw device backup or Flashbackup.  Consider this a last resort.

[Veritas-bu] Suggestions for large files?

2007-11-16 Thread Chris_Millet

Have you tried the backup already?  If so, what are the policy settings and how 
fast are your drives streaming?

LTO3 is rated for 70MB/sec native..more if the data compresses well, so make 
sure your backup server has at least 1000Mbps network connection and same goes 
for the client.  If your drives are streaming that fast or better already, you 
might be able to make it go faster by aggregating a second gigabit link on both 
servers to remove that bottleneck.  Then you could try to get two tape drives 
to do the backup by breaking up the backup selection in the policy into two 
chunks using the NEW_STREAM directive.

[Veritas-bu] T2000 vaulting performance with VTL/LTO3

2007-11-16 Thread Chris_Millet

I'm starting to experiment with the use of T2000 for media servers.  The backup 
server is a T2000 8 core, 18GB system.  There is a Qlogic QLE2462 PCI-E dual 
port 4Gb adapter in the system that plugs into a Qlogic 5602 switch.  From 
there, one port is zoned to a EMC CDL 4400 (VTL) and a few HP LTO3 tape drives. 
 The connectivity is 4Gb from host to switch, and from switch to the VTL.  The 
tape drive is 2Gb.

So when using Netbackup Vault to copy a backup done to the VTL to a real tape 
drive, the backup performance tops out at about 90MB/sec.  If I spin up two 
jobs to two tape drives, they both go about 45MB/sec.   It seems I've hit a 
90MB/sec bottleneck somehow.  I have v240s performing better!

Write performance to the VTL from incoming client backups over the WAN exceeds 
the vault performance.

My next step is to zone the tape drives on one of the HBA ports, and the VTL 
zoned on the other port.

I'm using:
SIZE_DATA_BUFFERS = 262144
NUMBER_DATA_BUFFERS = 64

Any other suggestions?

It depends on the drive and some other bits, but generally the 'st'
driver on Solaris is set up so that the 'c' or 'u' device provides the
highest density with compression, while the 'h' device provides the
highest density without compression.  (This isn't always true).

You can try it, but if you're working on a drive that doesn't have
external LEDs, it's not easy to tell if it's working.  I've never tried
to write uncompressed LTO3, so I can't verify.

Can I ask why you want to do this?  The drive shouldn't slow down or
expand already compressed data.  It has a check to just dump raw if the
compression routines try to expand.

This is especially true of NetBackup 5.1 since there is a media catalog on
the media server.  You might get away with just pointing a 6.0 media server
to a new master but I sure wouldn't do it on 5.1.

There is also a documented procedure somewhere for properly decommissioning
a media server from a master.  Make sure you go through this on your old
master or you will have issues when you upgrade to 6.x.

At a minimum, do a full uninstall of the NetBackup components, delete all
the hangover files if there are any, and then re-install the media server
pieces again.
