I've seen a couple of whitepapers out there on them, but the Sun Enterprise 
T5220 servers seem to scream as a media server. I'm actually redoing my 
NetBackup environment as well and I'm going to a Dedicated Master Server + 3 
Media Servers (each Media server in a different location).

My master server is going to be a reused Sun SunFire v440 to handle all the 
Database operations necessary on the master server. The media servers are going 
to be all T1/T2 based servers because of their superior I/O handling over the 
USIIIi/USIV/USIV+ (not to mention they're cheaper then those class of machines).

One media server is going to have 6 4Gb/s FC HBAs running, one will have 4 
HBAs, and the last one will 4xU320s.

Master Server will be Solaris 10 (SPARC)
Media Servers will be mixed (two will be Sol10 SPARC and one will be a 
Sol10_x64 server)

If you do go with Solaris, I cannot stress this enough... Disable tcp_fusion! 
Disable tcp_fusion! Disable tcp_fusion!

This little vixen was responsible for a big list of headaches with tape 
duplication, catalog backups failing, etc.

Subject: [Veritas-bu] Master/Media server input

Hi all,

Looking to replace some old hardware with shiny and new.  Wondering if anyone 
out there had some commentary on anything idiotic I may be putting down as my 
requirements ;-)

Backup software to be used:  Symantec Enterprise Netbackup 6.5, we'll be 
procuring 1 master server, and 2 media servers to drive a total of 600 MB/s 
aggregate to a Diligent Protectier VTL.

OS Options (any will do):
- Solaris 10 for SPARC for both Master/Media
- Solaris 10 for x86 for both Master/Media
- RedHat Linux Enterprise 4 for x86 for both Master/Media

NIC requirements (per master/media server):
- ~200 MB/s aggregate throughput required (real-world)
- Suggesting 4x1 GigE NICs (single team) with offload engines

HBA requirements (per master/media server):
- ~2x200 MB/s aggregate throughput required (two separate buses, one for read, 
one for write, yes we still duplicate to LTO3 physical tape)
- Either two single port 4GB HBA's or one dual-port 4GB HBA's

Bus requirements:
- 1 independent PCI-E (x2) bus at minimum for each single-ported 4gb HBA
- 1 independent PCI-E (x4) bus at minimum for a dual-ported 4gb HBA
- 1 independent PCI-E (x8) bus at minimum for a quad GigE w/ offload engines

Internal Disk Requirements:
- One raid-set of 500 GB of Raid 1+0 (usable), probably 10k SAS, for Netbackup 
catalogs on master server only
- A raid-set of 100GB of Raid 1+0 (usable), probably 10k SAS, for OS/other 
application data on media and master

Memory Requirements:
- 12GB for the master server
- 4GB for a media server

CPU Requirements:
- Equivalent of four dual-core CPUs for the master server
- Equivalent of two dual-core CPUs for the media servers

Thoughts (Paul Keating stay of it ;-)?

Cheers,
Jon
