Re: Recommended filesystem for 6TB storage
I agree with Hetz, it really depends on the use scenario of the FS. On a side note, if its a viable platform(solaris), I'd consider seriously ZFS. ZFS IMHO is one of the best FS's today. I can say from a personal experience that ZFS works well with large volumes(10TB+) (both size wise and inode count wise).

Re: Question about VMWare ESX and standard PC
Hi, The reason ESX demands scsi disks is because it uses SCSI reservation commands for locking. It happens in numerous scenarios . i.e When the vmdk is resized.

Re: Virtualization hardware - was (Re: Recommendation for software/hardware for virtualization)
Hi, CPU's: I assume you're refering to VT-x(Intel) and Pacifica(AMD) cpu extentions. Well, you can find a list of CPU models supporting these extentions here: http://wiki.xensource.com/xenwiki/IntelVT and AMD: Athlon 64 F* , All current Opterons Having said that, using hardware aided vm extentions does not neceserly boost one's performance (in many cases it worsens it), what it does allow though, is running unmodified Guest OS's under a hypervisor(i.e windows under xen). As for xen VS vmware(ESX) , there are many mixed benchmarks(vmware prohibits publishing benchmark results of its products) around the compared perfomance of these two, so I wont go directly into that. Having said that Vmware seems to be a more mature and polished product. Keep in mind that ESX is not a freeware and quite expensive , moreover it must have SAN or iSCSI as its storage. All in all, regarding specs it really depends on the type of load you're planning to do. But one thing is for sure, you can never have too much RAM and double importance goes for VM's.

Re: My VMWare 6 (beta) experience
If you run vm on a host with cpu that has frequency scaling( Intel Speedstep,AMD PowerNow, AMD Cool'n'Quiet), then you're affected by the following: http://kb.vmware.com/vmtnkb/search.do?cmd=displayKC&docType=kc&externalId=1227&sliceId=SAL_Public As to your point regarding desktop cpu's also affected by this - most cpu's today (desktop,mobile) have frequency scaling.

What I'm interested in hearing is whether the RTC bug was finally fixed. Under VMWare Workstation 5 when running on Debian with kernel 2.6.18, as well as on VMWare server (latest version) when running on Windows XP, the guest OS receives an incorrect interrupt rate for the real time clock (RTC). This causes a host of undesirable side effects. When running a Windows host (as I do most days these days, working on a big Windows development project), the clock keeps running forward. Every so often, the vmware tools thingy resets it back, which wrecks havoc in Visual Studio's makefile system. On Linux, however, the effects are worse. When running Linux inside the guest OS, the system mis-judges how long the keys are down on the keyboard, and produces auto-repeats in cases where auto-repeat is most unwanted. I ended up solving that one by setting the auto-repeat threshold to almost a second, but this is very annoying when you DO want auto-repeat. I would very much like to know whether this problem is solved in version 6. Shachar -- Shachar Shemesh Lingnu Open Source Consulting ltd.

Re: My VMWare 6 (beta) experience
Hi, The reason you experience slowdown in Vmware 6 (beta) as compared to Vmware 5.x is because as it names suggest - a beta. VMware 6 has extra debugging&tracing capabilities and features included into it, and these cannot be disabled in beta release. Actually the software tells you this when you power it on, and that it will result in lower performance. So there.

VMWare: Version 6 (Workstation) Build 36983. VMWare 6 has some really nice features when it comes to memory support (up to 3.5GB), USB 2.0 support, and other nice features (including a built in VNC support, although not features as nicely as in the latest QEMU). One of the things that really irritates me and the reason I'm writing this here is it's speed of emulating: Although my machine is not the fastest in terms of processors today, it should be pretty respectable to run one emulated session pretty fast IMHO. The Guest OS that I'm trying is: XP, Norton Antivirus, 256MB RAM, 8GB Virtual disk and thats about it (I use it for some tests). With VMWare 6, the emulation is DOG SLOW compared to VMWare 5.5.3 (latest stable). It's so slow, that to me it looks like I'm running XP with a 400Mhz processor with 64MB RAM. I do know that the beta has logging enabled, but 3 times slower compared to VMWare 5? I think VMWare Workstation is now entitled to the name "Bloatware". So if you run the beta version and see a significant performance hit, it's not your machine, its version 6 beta. Thanks, Hetz -- Skepticism is the lazy person's default position.

Any ideas? Thanks -- Not gonna be king of the world if you're slave to the grind- Skid Row
Re: asterisk requierments
Hi,If anything, I suggest you use the Linksys with 32MB ram , for exact version check the following link: http://en.wikipedia.org/wiki/WRT54GKeep in mind that these router are not x86, so you will have to check asterisk(or any other software you need) compiles/runs properly there. If you choose to go with Linksys, I suggest you check out the DD-WRT firmware which is found here: http://www.dd-wrt.com.Hope this helps.

Re: IDE RAID controller and software raid in linux
Hey,I agree that RAID 1 seems to be best solution for current scenario.With Raid 1 you recieve a really good data protection with very little performance impact(more about this below).On the other hand, RAID 5 is quite expensive and will result in performance penalty both on the CPU and IO. To emphasize on the diffrences in IO performances in RAID1 and RAID5, I will explain what happens in both Read and Write operations.Write Operation - Raid 1(Mirror): IO command is issued to first Mirror Member. As soon as the command is dispatched (before it finishes) same write command is issued to other Mirror Member. Which in fact results for much lower write overhead than often considered. In general the write degradation in 2-Way Mirror is around 20% versus single disk. Read Operation - Raid 1 (Mirror): IO is performed on the least busy Mirror Member. This means that in multiuser/multi threaded environments a meaningfull performance boost is achived in reads.Write Operation - Raid 5: IO write command is issued to all member disk in the stripe. In addition a parity of the written data is computated(CPU) and the output is written to one of the member disks(each time a diffrent disk).The overhead depends on the CPU you have and the amount of disks in your RAID. Read Operation - Raid 5 : IO is performed on all stripe members. Utilizing multiple disks. again in this case, there is an excellent performance. In summary: raid 5 is great if you must use more than 2 disks and want data protection with great read performance and somewhat lacking write performance(most of write performance penalty can be removed with ddidcated RAID controllers with own parity proccessor and write cache). Raid 1 is offers the best(only) data protection solution for 2 member disks and provides good write performance and great read performance. Note: I didnt talk about RAID 1+0 or 0+1 here, since I understood you're considering either Raid 1 with two disks or Raid 5 with more disks. If you really concerned about your IO performance, you do some homework first and analyze your typical workload(how much percent you spend writing/reading, Disk loads, bandwidth,etc..). Based on this data you should build you configuration, Or you could simply go with RAID 1. Good Luck.On 9/27/06, Rafi Gordon < [EMAIL PROTECTED]> wrote: Hello,I made some more research on this topic.I am thinking of a solution using linux software RAIDfor disk crash.RAID 1 seems the best solution for this. (am I right?)It works with disk mirroring. This means that the data is in fact duplicated and written to both disks. This of course sets a highload on the CPU and the data buses.So my question is:In practical terms, suppose we have 2 common 200 GB SATA-II disks (7200 RPM)buffer size 8MB, and about 8-10 ms average seek time for read/write (Or something like that). And suppose we have a 1GB RAM , onx86 (not 64 bit) with about 3GHZ CPU clock.And suppose we are NOT talking about servers but of acommon linux programmer environment. (But on which a disk crash is unbearable and there is management which may affordanother disk for that withouth hesitating).Will it be bearable to use such a solution ?Or will the machine be so slow that it will be unbearable ? I simply cannot test Linux RAID 1 performance becauseit invloves erasing data and formattin to create aRAID set.So if anyone have experience with Linux RAID-1, he is welcomedto respond.
