  1. I was wondering if its possible to move a array controller from one PCI bus to another (a 64bit/33mhz to a 64/66mhz) without damaging the arrays on the controller. The system is a Compaq DL580 G1, running windows 2000 advanced server. Will there occur any problems doing the operation? I mainly want it to run smoothly because its running the business CRM program and id like that to work after the operation Darking

    Moving a Compaq 5300 controller

    Well first of all compaq didnt set it up, rather our server provider did, and i dont have very good experiences with their setup of hardware.. honestly i think its a mistake that its in the slot its in atm. Secondly running a big controller like the 5300 series with 18 disks attached in a slower bus than its rated at, i personally find stupid. Its a real controller: Smart array 5304/128 And yes it should remeber the arrays, its not so much that, im more worried about windows plug and playing the controller as a new device(since it changes slot), and renaming all my drives!! But your right, i should check with HP before i do anything. Darking

    Strange behavior of RAID array

    As you mightve heard before HDTach is very bad at testing raid configurations. i suggest ATTO (it gives measurements like the above). I doubt its a controller issue or the fiber enclosure, we use the same, tho not fiber, and it works great. I forgot to add that i run my card in a 64bit bus at 33mhz (i plan to move it over to the 66mhz slot as fast as possible), and im not sure that 32bit 33mhz gives you that much bandwith to play with.. I cannot recommend changing the read write settings on the controller, since we did that once, and our sql server went crazy.. performance is best (for us atleast) on our server at 50/50

    Strange behavior of RAID array

    Yeah that sure helped Thanks alot.. Evidence: It just proves that a good correct driver is everything Darking

    Strange behavior of RAID array

    AAAAnd ofcause my writespeed went all to hell after installing windows 2000 SP3 on the server :/ Anyone know if it will help to reinstall the CPQARRAY driver??? Its a production server, so id rather not happy fellow anything up more than it allready is. Darking

    they perform pretty well compared the age (from 2001). Darking

    Why don't I get the advertised speeds?

    Yeah like people said DSL isnt shared, altho at your local phone central, the line that they hook up the dslrouters to is shared, and that can get saturated, but normally ISP's are pretty quick to upgrade those things, since its normally fiber or ATM. The high ping can be several things, since your using your LAN card now, i would first try updating the driver, it might be faulty and give odd ping responses (ive tried that myself). DSL speeds are also limited in bandwith by the distance from the phone central. To get DSL to work at all, the distance cant be more than 4KM, and if you expect to get 1.5Megabit/s i think its around 1.5-2KM max... 8mbit wich is the standards highest speed... well anything over 800 meters... dont get your hopes up. And yeah then there's PPOE overhead and stuff like that, but as honold said, its minimal Darking

    Help me help a friend :)

    Ah yes, i mightve mixed up the company names... But still for video editing, i should think a dedidcated card would be much better than adding extra processors and memory. Darking

    The only real thing about his current configuration im wondering about is, why doesnt he have a DV card for realtime editing... Ive seen high quality editing on a much slower machine than that, all it depends on is a good card.. Back in those days what i saw was something called a Pinnacle Raptor. I think its replaced with something called Pinnacle DV500 Plus. it costs around 600-700$. Darking
  10. Im gonna answer the questions the best i can (lousy memory ) Well its a pretty simple setup really... i have 15 servers of different types, SQL, exchange, file servers. All of them attached to the network currently via 100Mbit network adapters, All of the servers will be replaced this winter, for newer models with Gbe. The servers themselves are attached to a Procurve 4108GL switch, with a backplane of about 36GBit. Well basically its like this: 2 file server, around 600.000 documents, and different other types of files= 170GB 6 SQL servers, the biggest at 40GB database, all in all 65 GB database. 6 citrix servers, wich i just need to be able to Disaster recover= 30GB 1 exchange, with a priv.edb of around 10Gigs, and a pub.edb of around 1gig. and 2 servers doing different oddjobs= 10 gigs We have IDR, accelerator, agents on all our servers and ofcause SQL and exchange on the respective servers Alltho we generally atm. make backup of a flat dump file, and the logs, because of speed issues with making backup from the databases themselves. Our primary database server dumps to a internal DAS 3 times a day, but i only need to make one backup of it once a day. That was sort of also my idea sooner or later, im going to test the speed my backupserver gives me(it runs some printing jobs too but thats it) at first, and then im gonna make a trial copy on the storage server, to see what that gives me. I can see the benefit of removing the backup task from our "production" servers. But time will tell. Darking
  11. Hello all. I was wondering if i could get your ideas and advice about a disk system im going to build for my company, mostly for usage as backup system. its a basic 16 disk system, where i was planning the following configuration: 2x 8506-8 3ware Escalade controllers 16x 250gig disks, either WD or Maxtor 1 or 2 gigs of ram, and a good sized CPU. My idea is to make an array on each of the controllers like this Array 1 = Disk 1-7 in Raid5, Disk 8 as hotspare Array 2 = Disk 9-15 in Raid5, Disk 16 as hotspare Array 3 = Array 1 and Array 2 in Raid0. (windows 2003 software) This should give me a theoretical writespeed of around 80MB/s or more, and still keep the security and maximizing the number of disks actually used for storage. Only weak points i see in it, is a controller failure, or if the software stripeset explodes somehow. Gentlemen, what are your thoughts? Darking
  12. The biggest problem with a fiberchannel or SCSI DAS solution is the money. Ive tried looking around for stuff like that, compaq wich delivers our servers want over 50.000$ for one TB of storage. Its simply too high for our budget atm. plus i dont really need the big bandwith it gives me, 10-15MB/S should be sufficient. We will use backup exec 8.6 for our backup needs, since thats what i have exeprience in, and it has always worked well, with disaster recovery options and stuff like that. I know TSM is a solution that works like you describe, all tho i must admit that i myself am a bit nervous about those types of backups, i like to know that i have everything in one tape/disk etc. But grated its an option, altho TSM isnt cheap either, and i dont think i dare ask for a new backup program, since i just got Backup exec 8.6 last year Darking
  13. Im not aware of the 3ware controllers supporting 50.. Plus another problem is that due to certain limitations, you cannot make arrays larger than 3 TB on the controllers.. Therefor i will end up with a problem at around 12 disks if i use 250GB disks. Thats primarily the reason i made software strip, because the controllers cant make arrays over 3 TB Darking
  14. Well to be honest i doubt a 80MB/s writespeed is a requirement.. With 10MB/s i can still write the 300Gigs in five hours so im ok on that part. I must admit i hadnt thought of using raid 0 and the software Raid1 then, that might be a idea.. Will it matter greatly that i use 5400 RPM disks, compared to 7200 RPM? Since the price is alot different in those disks... And will the Cache be of greater importance, 2 or 8MB pr drive? Thanks for the good answers Darking
  15. Sorry for not stating the function, a slight error. Its basically storage for backup purpose. Meaning that i will make my backup from our veritas backup server, to the storage server. We need to backup roughly 300GB a day, and keep between 7 and 14 days, each weekend, a tape backup will be done from the storage server too. The backup window is 8 hours, and our current DLT simply cant do it in that emount of time. The big plus of a disk system is also the restore time. Unfortunately due to company policy the idea of incremental or differential isnt an option. I like the NEXSAN products really, but im not looking for a SAN solution atm, since its going to get way to expensive compared to a simpler NAS solution like the one im wanting to make. Darking
  16. What none of you smart folks able to help me with this post, or are you all too busy writing answers to folks who ask, if Raid0 helps them in gaming id rather know the experts opinion before i go out and invest 10.000$ on a server. Darking
