  • HP Smart Array p400i with Intel X25-M 160 SSD

    - by user67304
    I have a pair of x25-M 160 Intel SSD's in an HP DL360 G5 with a p400i Smart Array running 512 BBWC. The disk performance I am getting on this box and another identical one does not come close to matching the same two drives running through a cheap 3ware RAID card. Any idea? I have played with the cache settings, but nothing allows me to get the same results. It seems like the Smart Array controller is the bottleneck.

  • VirtualBox, physical disks, and snapshots

    - by noamtm
    I have an Ubuntu guest installed on a raw HDD (entire disk, not a partition). It runs just fine under WinXP. In addition, I was able to boot directly into it (using the BIOS boot-device selector). At some point, I have created a snapshot of the VM. I have made some changes since then. Today, after a long time, I tried booting into the "VM" disk. It worked, but all the data there is pre-snapshot (or, rather, frozen at the snapshot). Can I somehow merge the changes since I took the snapshot into the physical state?

  • Does software RAID 1 in Windows 7 improve read speeds?

    - by Rich
    As the title says, does software RAID 1 (mirroring) in Windows 7 improve read speeds? I'd like to set up RAID 1 to help protect my important documents (yes, yes, I know it's not a backup), but performance is also important to me. As I understand it, RAID 1 should theoretically be able to improve my read speeds by n times, where n is the number of disks. Is Windows 7 able to get this boost? I haven't been able to find out this information anywhere.

  • Dedicated hard disk for Informix SE dbname.dbs files & dedicated ramdisk for /tmp files.

    - by Frank Computer
    INFORMIX-SE 7.2: I would like to dedicate a hard disk, exclusively for my dbname.dbs directory which holds all the .dat and .idx files, and create a ramdisk for my /tmp temporary files in order to improve performance. I would also like to strip down the OS from any unecessary files and processes to minimize overhead for my dedicated application. Is this a good idea and are there any roadmaps for accomplishing this?

  • How does BTRFS compare to ZFS?

    - by Zubair
    I am considering which OS and filesystem to use on some new servers I have and am considering either Free BSD with ZFS, or Linux with BTRFS. The programs I have run on both systems, so the only issue is reliability of the filesystems and performance, etc.

  • How to fix Windows 2008 R2 show less memory than available

    - by eugeneK
    I've got Win2008 R2 64bit installed on Dell R410 server with 8GB of RAM. Dell Open Manage shows 8GB total and 4GB available for use, In Windows Control Panel, System i see 64bit and 8GB of RAM while in Windows Task Manager at Performance tab there is 4GB of memory available. Dell support has made some checks and told me that if BIOS shows 8Gb of RAM and indeed BIOS does then it's operational system issue. Tried to search online for resolution but none found. Please help, thanks

  • Connection Filtering with Multiple DNSBL's?

    - by JohnyD
    Is there any advantage or disadvantage to using multiple DNSBL's with ones connection filtering? I just switched from SpamHaus to BarracudaCentral but have added in SpamHaus to test for increased effectiveness. So far there is no dip in performance and no increased load on our SMTP server.

  • How to maintain a SSD drive on Ubuntu ?

    - by Julien Nicoulaud
    I am running Ubuntu 10.04 on a Intel X25-M PostVille 160 Go SSD drive. How can I tell if there's something wrong ? What should/can I do to maintain its performance/health ? Should I use TRIM and how often ? This may look as a duplicate of this question, but I am more asking in term of good practices and learning how to use this new technology the right way...

  • Which is a better use of my SSD Drive [on hold]

    - by RS Conley
    I have the choice of setting up a system with two SSD Drives in Raid 1 mode as my boot drive for Windows 7 64-bit. With the Program Files and User Folders moved to a Second regular HD Drive also configured using Raid 1. Or Setup a single SSD Drive (120 GB or 256 gb) as a cache Drive using Intel Rapid Storage Technology combined with two normal hard drives configured as Raid 1. Which setup would have the faster hard drive performance over the life of the computer?

  • Why is the Task Manager Total Physical Memory not 2048 MB or 2 GB

    - by Dorothy
    I found 3 numbers for the Total Physical Memory: In the Task Manager under the Performance tab: 1978 MB In Computer Properties: 2 GB And running wmic computersystem get TotalPhysicalMemory /format:list in the command line: 2074554368 Bites Number 1 matches Number 3 except Number 1 is rounded. When I convert Number 3 to GB 2074554368 / 1024 / 1024 / 1024 I don't quite get 2 GB. I get 1.93207932 GB. Why does Number 1 and Number 3 not match Number 2?

  • Will my internet address for my internal site cause my traffic to go external?

    - by Toby Allen
    If I have two domains pointing to the same machine, but one resolves to an internal address and the other to my internet facing router, will there be any differnce in route taken to my machine (primarily in terms of performanc). eg. internal.mydomain.com resolves to 192.168.1.200 external.mydomain.com resolves to A.Web.External.IP both eventually resolve back to the same machine. For a client in the network, will using the external address give a performance penalty?

  • Optimize SAP SQL Server database using DTA

    - by Danilo Brambilla
    Is it safe to optimize a SQL Server 2005 SAP R/3 database using Database Tuning Advisor raccomandatations? We are experiencing very low performance on a dedicated SAP database because of intense read operations ad the db and DTA suggest to create about 25 indexes and 100 stats. I am not an expert of SAP and I am quite surprised to see that this database has about 56.000 tables and 6500 views (120 GB of data). Thank you all for help

  • View Public Key in Domain Key for a Domain

    - by Josh
    Using Jeff's blog post I'm creating domain keys for my account. I wanted to verify the setup using Get or Host command with Bind for Windows but I'm lost one of the commands. I can see view the _domainkey. txt file with this command: host -t txt _domainkey.stackoverflow.com but I'm at a loss at how I'd find the selector record. Jeff points out it can be anything before the before the period in "._domainkey.domain.com" but how would I list all records if I didn't know the exact query name? Is there a wildcard I could use to view all TXT or all records under this section?

  • Windows7 issue in mutli- tasking and memory

    - by Nitesh
    I seeming some problem in my windows OS recently, let me first say my system configuration. processor - Intel(R) Core(TM)2 Quad CPU Q8400 @ 2.66 GHz Installed memory (RAM) - 4.00 GB (3.00 GB usable) System type - 32 bit operating system I am using two OS in this system, first one is Windows7 and the other is centOS. Well, I am using this from a long time there was no problem , and all of a sudden since from couple weeks I am facing problems in my Windows7 OS. In windows7 i was nearing using multiple jobs almost every time i log in, there was no problem but now i don't no what happen I am not able to do multiple jobs at same time. For example- 1 I am now not able to listen to music in windows media player and view photo's. All of a sudden the system stops working and does not respond and then respond after 5mins and the music get played where it got stopped after 5 mins. 2 When i start browersing internet it hangs all of sudden and doesn't respond for 2 or 3 mins and gets loading. I mean it just happens for every operation i do in the system. Even now typing was also difficult, it gets hanged very frequently even though i am doing single task. I have never come across this kind of problem before. So the first thing i did was to see the useage of the processor and the memory. Well, i thick the useage of the processor was fine, for single task the useage was some where around 3 to 5%. Well, it was something weird i found in the memory, in spite of no task that i was running it was using somewhere around 34 to 41% of memory. So i opened the task manager and click on resource monitor in performance tab. And in the memory section of the monitoring tool i found the usage of my RAM, it was something like this. Hardware reserved - 1029 MB In Use - 1430 MB Modified - 49 MB Standby - 1566 MB free - 22 MB And i could also see Available 1588 MB Cached 1615 MB Total 3067 MB Installed 4096 MB well, this if all i could find out and i have no idea why my computer is acting so weird all of a sudden and the performance problem is growing day by day and i also don't know if there is problem in Bios, i have let it for default settings from long time. please help me and Thank you in advance for reading this and helping me.

  • How does virtualization improve server utilization?

    - by Continuation
    The biggest benefit of virtualization is usually said to be improved server utilization. But why do I need virtualization for that? Say I got N physical servers that are lightly used. Why don't I just combine all the apps on those N servers into 1 physical server? This way I don't incur the performance penalty of virtualization. What does virtualization buy me in this case?

  • Windows 2003 X64 Std page file usage

    - by duhaas
    Just trying to understand why I'm seeing what I'm seeing on this system. Pagefile performance counters are telling me i'm @ about 1.5% used with my page file, settings for the file are 2GB-4GB, but task manager was showing 13GB usage: Oddly enough, it just sunk down: This machine has IBM DB2 9.5 workgroup edition running on it. Thoughts??? Actually, just learned the developer had just stopped DB2, hence the huge drop, just not understand the difference in the PF usage in task manager vs perf counters?

  • How should I interpret the specifications of a SSD?

    - by paulgreg
    When considering to buy a SSD, how should I interpret the different specifications of the SSD? Here are some specific things that need to be deciphered: Controller (this can affect performance and endurance more than all other factors combined) Bus Technology Form Factor (Physical Size) Capacity NAND or NOR technology Power Consumption during Read, during Write, when Idle Read/Write Burst and Sustained Throughput All of these things I would like to be explained in more detail and their actual importance in selecting an SSD.

  • Is Oracle Smartscan really effective?

    - by Vimvq1987
    Oracle is marketing Exadata to our company, and they're focusing on Smartscan, which is, advertised 10x more effective than traditional solution. I don't really understand (and somewhat don't really believe) this solution, because they assume that data is put on separated storage, and no indexes are used, so "1TB data was scanned and only 2MB is returned". So, I want to ask you: is Smartscan really effective. Is it true solution that greatly improves performance or just a buzzword? Thank you so much for your experience
