ASM vs RAID for RAC 11 GR 2 environment

Hello!
We plan to install 11 GR 2 CARS with two-node Cluster on LINUX in our environment.
Operating system: OEL 5.4
In our material, we got two dell servers with 16 GB of RAM on each side more on SAN we have only 8 (173 GB) disk left for RAC Cluster configuration. I create the database (LIVE/UAT) on this Cluster Setup. Currently our Production DB dimensions are 6 GB and I assumed that for 5 years, that he's not going beyond 100 GB coming and I keep size UAT 15 GB difficulty without modification. So, how do get you the best performance from ASM using my all resources.

My question:
(1) who is the best solution for the ASM and RAID in our storage environment?
(2) disc how do I create a group for the two databases (UAT/LIVE)?
(3) records how much should I allocate in each group of disks with RAID Option or if all this suggests for LUNS, how to create LUNS on the disk I got?
(4) I know oracle recommends two DATA DISK group & FRA is there any suggestion of CRS, REDO and TEMP FILE?
Thank you for your Assintance.

Nadège.

My first question was: which RAID Option (0,1,5,0+1) I choose with ASM?

Well, it does not matter for the DSO. At least in your configuration with 8 disks.
RAID0is not an option - forget about it. RAID1 (or combined with more than two discs and a RAID0 superimposed making it a RAID 1 + 0) could be an option for the writing intensive databases. RAID5 is more for intensive reading due the RAID5 write hole but offers a capacity of 'more' at the expense of slower writing speed.

I have recommended to the stick with RAID1 (mirroring two disks) and exporting to ASM rather than create a big RAID1 + 0 on all of your discs and exporting as a big Chuck of ASM storage for the management of. If you want to add storage lateron your perfect according to the recommendations of the Oracles have LUNS of equal size in ASM with two mirrored drives. If you create it large RAID 1 + 0 and lateron add two drives you have a 600 GB size logic unit number and a 170 GB size... it's a big shift.

But if I create TWO group of disk then, is it advisable to provide two data bases (UAT/LIVE). ?

Normally, there is a separation between UAT and P on the storage and the server level. In your case, it might be 'ok' to do everything in the same disk group. It depends especially of what database puts the load on the disk subsystem.

    Hi all.

    I was wondering, what is the best configuration of RAID for ESX 3.5 performance?

    I have a HP DL360 G5 Proliant with several SAS drives.

    It will be better to make a RAID 5 o RAID1?

    Thank you!

    There is no best RAID for ESX. Depends on VM disk usage profile - so if you plan to install SQL server and then create RAID appropriate for SQL server.

  • Recommendation of RAID for Equallogic iSCSI SAN?

    We look at a Dell/Equallogic PS6000E with 16 drives of 1 TB, it connects to our servers ESX 2-3 (about 15 virtual machines running) and to a SQL cluster (mainly a SharePoint service workload size).  Dell recommends RAID5, which would give us ~ 12 useful to.  Frankly, if we had used 8TB, that would be fine.  Any recommendations for the best RAID for Equallogics level?

    Thank you

    Chad

    If you can really just 8 to, I must say raid 10...   Reference Dell suggests always raid 5 no matter what.

    Now best practices is to create several groups of disks with different raid levels for the taste of storage at your fingertips.

    You are going to have to make some calls to judgment on how to implement.     I suggest you test conversions PtoV tour and play with the config some before deciding, but I know that it is now possible in most cases.

    Dell has an excellent white paper on the table.  It's for the MD3000i, but the raid types and most other info still apply to the DAS or san during raids.

  • Upgradation OS for RAC

    Hi guys... How is everything...

    I have the node CCR on Windows2003R2 Itaniam. I need to know is there any procedure for upgradation OS for RAC... I mean I'm going to the bottom of the Cluster & when the OS database places a gradation.

    Hello

    you need not stop the entire base.
    Upgrades of the OS can be in upgradeable mode (so one node after another), you must stop the instance and the clusterstack on the node, you perform the upgrade.

    Policies to support Oracle to launch of the CARS with different versions of an operating system within a period of 24 hours.
    In other words: after completing the upgrade of the first node you have 24 hours to what your other nodes must be at the same level of the new OS.

  • Storage shared by NFS for RAC

    Hello

    I intend to set up a node 2 CARS. However, I have only the internal drive to use and no SIN /SAN. So I intend to share some of the ability of alternatives I have on the internal nodes 1 & 2 discs and make shared storage using NFS. However I have a few questions about it.

    Q1. Since the NFS mount will indeed be file system media, this means that for the storage for the Cluster option and the RAC database that I can only use option 'shared file system' and not 'ASM '?

    I think what is confusing me is that I think that I read that the ASM disks can be complete physical disks, partitions of a disk, SAN LUNS or NFS?

    If this is the case then it suggests that I can create an ASM disk based on a NFS mount?

    I don't know how to do this - any help / advice would be appreciated because ideally, I would have preferred to create candidate ASM disks based on the shared NFS disk

    Thank you

    Jim

    You can use NFS as your clustered file system, but if you want to use ASM we top of the page so it no problem: dd to create large files on the file system shared, for example,

    If DD \u003d/dev/zero of = / mnt/nfs/asmdisk1 bs = 1048576 count = 2048

    and set your asm_diskstring parameter to point to them (or specify them as devices to be used at installation time). It is very easy to set up and is fully supported by Oracle of the uncle. I recorded a few demos that include this a year or two before, Oracle ASM free tutorial

    Start it as seems to be available on the other node, tell the user of ASM:

    Start SQLplus / as sysdba (or sysasm)

    SQL > ALTER DISKGROUP MOUNT;

    See if it works, if not: post the result.

    What other RAC DBA must have ROOT access to?

    AllYourDataBase wrote:

    In other words, you must either trust your DBA to not be malicious / inept and accept the fact that they have root access, or not give them sudo and form your system administrators to manage the grid infrastructure.

    Agree.

    On all databases, that I never managed, even in the era of mainframe, was my sysadmin/root access in order to exercise my DBA functions. Often service waiting too for sysadmin is not available. Similarly, the sysadmin also often held in a DBA when I'm on vacation or unavailable.

    It is a partnership - both parties have the same goals and objectives. A stable and robust and functional environment.

    Set up the walls between these parties on behalf of the so-called security policy? My point is that will be invariable cause more problems than what it addresses. And I've seen it in other departments - where a minor problem takes several days to resolve due to the wall (and distrust) between sysadmin and s/n, regardless of the amount of paperwork needed to get real results as the responsibility and accountability are ignored by both parties.

  • Silent, quick config RAID for Mac Pro DAW

    I'm looking for ideas for storage configuration for my Mac Pro ' 09. This is the heart of a campus radio station / recording studio. The machine is a beast, and it serves my purposes very well. That said, the storage on board certainly needs an upgrade. Recently, I ran DriveDx to check the health of disks, and several of them are almost 30,000 hours. Right now, we lack a RAID 0 2 x WD RE3 750 GB (circa 2009) and 2 x Seagate 750Go (to 2008). Disks run without problem, but they are relatively slow and old (max ~100MB/s WD; ~75MB/s Seagate). In addition, I'm really not comfortable running a raid interlaced offshore of different styles of hard drives.

    I am looking to buy four new disks. Here's my wish list:

    Minimum of 1 TB of capacity

    Optimized RAID

    Reliable

    Quiet

    Relatively fast

    Not horribly expensive

    Does anyone have advice? I've been looking around for a while, but it has been difficult to find a good combination of these features. Or, if you have any other ideas I'm open to that as well. Thank you!

    Mac Pro 4.1

    2.26 GHz 4 x 2

    32 GB OF RAM

    3 x GeForce GT 120

    You can install one or more SSD Drives slightly faster than the 375 M bytes/s supported by the drive bays and get excellent results and not need a RAID at all.

  • Re: Need driver XP SATA/RAID for Satellite Pro U400

    Hi all

    I've searched and searched, but I can't for the life of me find suitable driver to install XP on my machine. It came pre-installed with Vista which is useless to me because of the instability, bugs, just be a poor OS. I got the new laptop for a week now and have not been able to use again, so it would really appreciate someone pointing me in the direction of SATA/RAID drivers for XP.

    Thank you!
    E.g.

    Hello

    The Satellite Pro U400 needs a SATA driver, and you can find it in the Intel Matrix Storage Manager package.

    This storage manager can be downloaded from the European driver Toshiba page (see the series of portable different) or you can also download it from the Intel site.

    The SATA driver must be installed during XP Setup process. You must press the F6 key to include a 3rd party (SATA driver) from the external USB floppy drive.

    If you don t have a floppy drive, then you could create a clean XP CD with SATA driver. NLite freeware software can be useful for these jobs

    My advice is; Google a bit for nLite for more details.

  • 16 disks table PS5000 Sata - Raid for better performance and more capacity

    Good afternoon all

    I studied the whims of the various raid options and I was wondering if anyone has any practical idea using tables PS5000 SATA?  Basically, the table will backup disks to virtual machines as well as Raid would be preferable for the performance and capacity?  I was thinking 50 Raid or Raid 6, that the table is at a distance of my office in one data center so that there could be 2 failures before the disaster...

    Thank you very much

    Eric

    Hi Eric,.

    'best' depends entirely on the expected I/O model.  Small random writes should use R10.  RAID50 is usually a good compromise on space and performance.  But it has the risk of a double RAIDset faillée down.

    Another factor is that the PS5000 is end of life.  No support, firmware or parts of long term.  Help to off the shelf drives add uncertainty to the reliability of the table.   I would never use one of these for primary production so data.  To provide the best protection in this case, I would use only RAID6.   R10 would be down, but may suffer and failed with two failed disks in the mirror of the same value.

    Kind regards
