RE: [Veritas-bu] Master and Media HW and OS..

[Scott Jacobson]

Johnny,   Can't say I share the same opinion regarding issues with Linux running as media or master servers in a NetBackup environment.   I've been using Linux (SLES 8/9) media servers in a SSO environment with ACSLS for the better part of a year and a half and haven't had any major issues.  Sure, setting it up was challenging as there wasn't definitive documentation at the time.   My media servers are a 2 x 3.4 MHz (multi threaded) using either Intel/AMD with 4 Gb of Ram driving 4 FC LTO II tapes drives (thru QLogic HBA's) with two 1 Gb NIC ports bonded together.   No problems here.   Scott J. >>> "Johnny Oestergaard" <[EMAIL PROTECTED]> 1/24/2006 1:11 pm >>> I don't know anything about Linux, but in our installation I use Windows 2003 on my combined master/media server. The server is a Dell 2850, 2 x 3,6 Ghz HT Xeon CPU's. I use 2 Emulex LP10000 HBA's to give me access to the SAN (2 connections to disk and 2 to tapes) and one Qlogic HBA to connect to the library. Connection to our LAN is at the moment 2 Gbit/s The server feeds 4 STK9940B drives Except for the LAN connection I really don't have any problems with performance. Daily backup volume is around 2,5 - 3,0 TB from 80-100 servers running anything from NT 4.0 to Windows 2003, Exchange, SQL, SPS, BizTalk and God knows what. I even have a bunch of VMware ESX servers. After I migrate to NBU 6.0 I will add one extra media server and share the drives using SSO.   Windows isn't the best operatingsystem for have I/O load, but I don't want to migrate to Solaris because of the extra cost and also don't want to use Linux because I am the only one who knows anything about Linux in our shop. And we have to pay a lot more for a RedHat ES server licens then what we pay for a Windows licens (NBU cost is the same for Windows and Linux)   From all what I know about performance on an Intel box (or AMD) you would get a decent performance out of any box now-a-days for NBU use. I would go for a 4 CPU box using Xeon processors with 4 GB ram, some good HBA's and some good NIC's if I had the money. But a 2 processor box as the one I use can feed 4 drives in my installation without any real problem.   Even if my info is from Windows, I hope you can use it.   /johnny   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Hampus Lind Sent: 24. januar 2006 20:05 To: veritas-bu@mailman.eng.auburn.edu Subject: [Veritas-bu] Master and Media HW and OS..   Hi,   We run all our master and media servers on HP PA-RISC server and HP-UX as OS. These servers cost a lot, not only to buy, but also in maintenance.   What do you guys think about going from the above to powerful INTEL server with linux as OS instead in a datacenter environment? We have about 200 clients and (all full is about ~15TB, never at one time though) to backup at one of our sites.   Anyone using this type of solution in DC env`s? Recommendations??   Thankful for advice, MVH / Hampus Lind Rikspolisstyrelsen National Police Board Tel dir: +46 (0)8 - 401 99 43 Tel mob: +46 (0)70 - 217 92 66 E-mail: [EMAIL PROTECTED]
