RAC storage requirement

Hi all,
We are in the process of evaluating ASM/RAC as an HA solution for our oracle databases 11gR2 hosting.
But, one thing isn't clear for me: have a shared storage (SAN or NAS) between all nodes of the cluster is mandatory
or ASM can do replication between nodes?

So you must have shared storage and then you can configure ASM on that.

  • Is there any value for free storage requirements to SQL Server 2K8 R2 to run?

    Grettings
    we have a SQL Server 2K8 running on a Server that has less than 10GB of free space.
    Do we have a problem with that? what is the storage requirements to SQL keep running normal?
    Thank you in advance

    Hi LmmLopes,
    If you are talking about 10GB free space on the primary drive I think you should be able to run your SQL server without any issues.
    Please find the chart below for the Hard disk requirements.
    Hard Disk Space Requirements (32-Bit and 64-Bit)
    During installation of SQL Server 2008, Windows Installer creates temporary files on the system drive. Before you run Setup to install or upgrade SQL Server, verify that you have at least 2.0 GB of available disk space on the system drive for these files.
    This requirement applies even if you install SQL Server components to a non-default drive.
    Actual hard disk space requirements depend on your system configuration and the features that you decide to install. The following table provides disk space requirements for SQL Server 2008 components:
    Feature
    Disk space requirement
    Database Engine and data files, Replication, and Full-Text Search
    280 MB
    Analysis Services and data files
    90 MB
    Reporting Services and Report Manager
    120 MB
    Integration Services
    120 MB
    Client Components
    850 MB
    SQL Server Books Online and SQL Server Compact Books Online
    240 MB
    But if you are talking about the 10 GB on the entire server. Then you need to consider the database size and its expected growth.
    You can consider adding additional disk drive and use it to store the data files.
    Hope this answers your question.

  • Smart Storage requires hard drives before configuration

    (From Davin Oishi)
    Issue/Question: Unit powers up,  but can't login to web administration GUI
    Resolution: The Cisco  Smart Storage products require at least one hard drive to be installed  in the system before configuration is allowed
    Issue/Question: Why does the  Smart Storage require a hard drive to be installed when my previous  NSS3000 did not require a hard drive before configuration could be made
    Resolution:  The architecture for both product families is different.  While  configuring a device without drives does provide the ability to  configure basic settings before deployment.  The actual usefulness is  still limited to when the device has drives.  Smart Storage takes  advantage of the drives by placing configuration and applications on the  hard drives.  If additional drives are installed after initial setup,  configuration information is striped across the additional drives as you  add them.  This allows for better utilization of Smart Storage memory,  improves system performance, and allows for higher scalability.

    With eSata not going to be an option for all 3 drives. I'll use eSATA for the 2 TB and daisy-chain the other 2 with FW800
    I'll use the 500GB for Time Machine, but which would be the better plan?
    A) Put stills on the 1TB and use the 2TB for FCE scratch drive and back up the compressed camera data on DVD's
    B) Use the 1 TB for camera data and then either folders or partition the 2TB for camera imports and FCE scratch drives,
    In either plan the AVCHD files get converted at log and transfer and the h264 data gets converted via 3rd party conversion software. In both cases the converted files end up on the scratch drive.
    I should also mention that I plan to use QT not self contained exports and keep them on the internal drive. I am currently keeping disk images of finished projects on an external hard drive, unsure what to do with them. maybe I need an other drive or not bother with saving disk images ?

  • OIM Data storage requirements

    I was wondering if there are any thumb rules to determine how much data will OIM generate. Is this dependant on number of user profile for any given number of transactions. Also, if this data can be broken into different categories such as identity data, provisioning data, audit-trail data etc?
    We are in middle of defining our data archival strategy and need to understand data storage requirements.
    Thanks in advance for your input on this.

  • Does Manage Storage require wifi?

    Shock of shocks--discovered today that Manage Storage requires WiFi being on!  Is that right?
    i'm talking about getting the list of apps on the device and seeing which are the memory hogs--not doing anything with iCloud.  In the past, it always came up regardless of whether WiFi was on or not, the list would come up.

    It's weird because on my iPad Mini 2, after I installed iOS 8.1.3, I was unable to get a list of apps on the device and their space consumption.  I had to turn wifi on to see it!
    Is there a bug?  I've had instances on different iPads, this one, too, in which the phrases about iCloud are not in their proper place.  I'm wondering if the Manage Storage button that was displayed was the one for iCloud and not the device itself.  It was showing the device's capacity and remaining space--not the 5 gb for iCloud.  I also didn't have iCloud set up (still don't).
    Today, fortunately, it worked even with wifi off. 

  • 10g RAC Storage knowledge for I/O tuning

    Gurus,
    With 10g RAC lot of DBA's require more and more knowledge of storage like LUN,LUN TUNING,IO TUNING.
    Are there any books that teach information like
    1.Best practice for ASM.
    2.LUN configration steps and best practice.
    3.I/O tuning.
    I am facing lot of issues with I/O responce times in RAC with ASM environment.Most of the time the responce
    time is more than 10ms but its very difficult to explain and get proper feed back from SA and Storage teams.
    Any advice how to gain more knowledge and resolve IO issues.
    Looking forward to get a very techinal responce from Gurus :).

    Learning Oracle,
    I don't think this or any other Oracle forum is a place for free consultancy, especially if you don't specify any details.
    Richmond Shee and others have published a book on the Oracle Wait Interface, it is pretty indispensible.
    Oracle Press has also a book on ASM out.
    As this is not the place to post free abstracts of books, made by volunteers, I suggest you visit sites lke www.amazon.com or www.bn.com or whatever vendor you have access to.

  • Oracle10g RAC - aio required?

    Greetings,
    we are trying to install Oracle 10g RAC on 2.4.20 based Linux distribution. According to http://www.puschitz.com/InstallingOracle10gRAC.shtml at least two additional components need to be installed: Oracle Cluster File Systems (OCFS) and Automatic Storage Management (ASM). Both components require aio, it's configurable for OCFS (compiles with configure --enable-aio=no), but looks like it doesn't for ASM (though it can somehow without asmlib).
    Is that true?
    Does it mean that 10g RAC can't be installed on pure 2.4.20 (without aio support backported from 2.6 by RedHat)?
    If not - could you please suggest the way to proceed with installation?
    btw is there official 10gRAC installation guide somewhere?
    TIA,
    Gennady

    Sun would not recommend using Oracle 10g RAC without Sun Cluster. Setup for that configuration would be found in the Sun Cluster Data Service for Oracle 10g RAC and the Oracle installation manuals.
    The installation of Oracle Clusterware alone would be documented in Oracle's manuals. If you have any problems with that, you are better off asking Oracle.

  • Oracle VM 3.1.1 storage requirements

    Hi,
    I was told that OVM 3.1.1 absolutely requires a external storage to operate. After consulting ther hardware requirements for OVM Server and Manager, I did't find out anything about this issue.
    Can anyone clarify this point for me?
    Thank you.

    Yes, local storage is OK as long as A) its on a supported adapter that presents a /dev/sdX file (versus stuff like a cciss device) and B) the local disk stands alone (you will need atleast TWO seperate disks to do this). Oracle VM cannot share the OS disk with a storage repository. The storage repository MUST be the only partition on the disk.

  • Oracle RAC Storage Migration - HP EVA to HP EVA

    Hi,
    We are in the process of migrating from an old HP EVA4000 to a new HP EVA6400. We have migrated most of the systems that had storage presented from the EVA4000 with the exception of our Oracle RAC databases and wanted to check to see if anyone knew of any gotchas before we proceeded.
    We are using CA to replicate the LUNs that are presented to the Oracle cluster. My plan is to shut down the database and all associated RAC services, disable CRS then halt the servers. I will then present the CA replicated LUNs to the servers and initiate a failover. I will then restart the servers and check that the LUNs have appeared from the 6400 before manually restarting CRS and the databases. I will then re-enable CRS before rebooting again to check that everything comes up automatically.
    Does this sound correct? Has anyone done this before?
    Thanks in advance.
    Phil

    Seems reasonable, but can't be certain unless you test. Make sure you backup OCR, VOTE, Database before you change the storage allocation.
    How big is the database ? How long will your downtime be ?
    It may be cleaner to just reinstall CRS and restore the database from backup ?
    Are you using ASM ? If so then you could just add new devices to ASM, migrate the data, then remove the old devices.

  • RAC Storage Options ( Openfiler or Wasabi )

    Hi RAC gurus..
    I need your advice regarding storage options for our RAC development environment.
    Since it is a development environment so management is reluctant to invest in SAN , Our production is a 2 node RAC on windows 2003 server mounted on Dell SAN.
    We have two spare servers available with Intel Xeon processors and SAS disks on them. SAN is out of question here and since we are on windows we cannot use NAS.
    I was reviewing the storage options and came across to Openfiler and Wasabi Storage Builder softwares which can transform your server ( spare ones ) into virtual SANs for shared storage purposes.
    I want to know if its reliable, scalable and whether it can be put to production one day or not? Which one is better Openfiler or Wasabi ?

    whether it can be put to production one day or not?
    you need to ask this to oracle support to get a correct answer ; moreover for a production system, I will only use certified hardware .

  • RAC Installation Requirements

    Hi Gurus
    We would be thinking to install RAC for new application.
    My requiremets are as follow.
    These are all general requirements and no specific to OS and any thing
    1> What could be the Hardware requirements (Like Nodes should be same hardware or change can also possible in RAC)
    2>Software requiremets (Like what all softwares are required for installing RAC,Any software depedency)
    3>Network requirement
    and last one
    Can i have different node in RAC as 1 node running in London and other in New York ?
    Thanks in Advance !!!!!!
    Regards

    You should be able to find most of your answers in the "Oracle® Real Application Clusters
    Installation Guide" - for 11g R2, that document can be found here. See Chapter 1 Section 2, "Overview of Server Hardware, Network and Operating System."
    Although not required, ideally you would want the hardware configuration of each node to be identical. However, it is entirely acceptable for the hardware configuration of each node in the cluster to be configured differently (different number of CPUs, physical memory, etc.). Oracle recommends that the Operating System release/version/patch level be the same on all nodes in the cluster.
    As for your question regarding the distance between nodes in a cluster, there is the concept of a "[Stretch Cluster|http://www.google.com/search?source=ig&hl=en&rlz=&q=oracle+stretch+cluster&aq=f&oq=&aqi=g1]," whereby nodes in a cluster can be placed up to a finite distance apart from one another to prevent situations where the loss of a data center takes out both/all nodes. The distance between London and New York likely exceeds the limitation for a stretch cluster, though. You could perhaps consider having two clusters: One in New York and one in London and having Data Guard set up between them. ;-)
