ASM with two SAN.

We are in a phase of re-architecture of our databases and all recently, we had the 4th SAN blip since a SAN has existed in our shop.

We are contemplating having two different SEM (maybe even from different vendors) to remove the single point of failure. Yes, our SAN was sold as a' double' and could never break SAN. BUT still, it shares the same firmware that of course after a firmware upgrade blew his brain when he was trying a failure more leaving us with a 'brown' failure (hum down half of the systems, a quarter in a State of funny and a quarter). 4 outages, 3 different brands of SAN.

I read some stuff on ASM but am not finding a clear answer, I can mirror all data flows to our Oracle for two different SAN databases so that doesn't break 1 SAN, SAN 2 takes over without any loss of service? Or would still need some Dataguard or something to make it work?

Thanks for any answers in advance.

Paul.

Yes you can do it with the installation of the ASM diskgroup as normal dismissal. Explain, you create two failgroups has a single call and another call B. In A failgroup you would put all the SAN disk/LUN has and in failgroup B you would put all the disk/LUN SAN B.

We had the same problem with a SAN failure we have converted our group of ASM disks in normal redundancy of questions the firm failure.

If you send me your email, I can send you a document I created during our tests, so that you can get more understand the possible configuration.

  • SRM with two HP Lefthand P4500 Iscsi SAN

    I'm in the middle of SRM with two HP Lefthand P4500 and I have a few questions. I will award points to the answers.  I need to build the site of the DR at the main location because the MPLS between HQ and the Dominican Republic will not be ready for a month or two.  (1) can I build on Esxi hosts, DR SAN and configure SRM on the HQ site or should I wait for the SPLM is connected between the two sites? (2) the customer plans to use an MPLS of 10 Mbps between sites; is it a big enough to tip of VLAN stretched between sites? (3) what is the best far from approaching my situation?  Finally there is someone out there who has installed SRM between two HP LH the's 4500 that can give some advice?

    I have SRM with P4500 LH installation.
    It is quite simple and a good start would be books Mike Lavericks SRM, because they have step by step guides to configure the NHL P4500 with MRS.

    I use VLAN stretched if you can get it, because it will save a lot of hassle in the recovery of your infrastructure.

    If you have any questions you can DM me.

  • ASM on HA SAN FC switches and replication

    Hello

    We need to install our first CARS, and we do not know how to manage the shared storage with high availability requirement.

    For example, we have a SAN HA with two FC - switches and a master - / slave storage configuration - is ASM able to handle this?
    ASM can handle physically separate physical disks (for example two boxes of discs in different rooms) and mirror and intertwining above?
    The drives are of different types: e.g. a disk array and drives normal and grouped?
    Any help is appreciated.

    Kind regards

    Yes... ASM can manage Luns Avaliable in host.

    ASM can handle physically separate physical disks (for example two boxes of discs in different rooms) and mirror and intertwining above?

    Yes... ASM can do

    The drives are of different types: e.g. a disk array and drives normal and grouped?

    It is not recommended that you have different (size and perfomance) disks on diskgroup even, you can have the serious performance problem.

  • Two R810s, each with two 8Gb Fiber Channel HBA + MD3620F + MD1220

    Hi people.

    I am planning an installation on this end, and I'm tender hand in the hope that the community can help me carry this all together.

    To explain, I have two servers Dell PowerEdge R810, each with two 8 GB HBA Fibre Channel adapters.

    I also have a Bay SAN of Dell PowerVault MD3620F 8 Gbps, with two controllers.

    I also have a Dell PowerVault MD1220 DAS SAS Expander Bay.

    I think to connects both R810 servers directly to the MD3620F, in order to consume all ports of four CF on the MD3620F. That is, one in each controller, from two HBAs in each server. (I can do this, or do I need a Fibre Channel switch? The MD3620F has 4 available ports, 2 per controller, so it would seem to be a natural configuration for only these two servers)

    Then, I will link the MD1220 to the MD3620F, so that its readers are also accessible through the two R810s on the link of Fiber Channel 8 Gbps. (what is the process to connect a MD1220 to a MD3620F?)

    Thoughts, tips, suggestions?

    Thank you

  • The use of frames with iscsi SAN

    Hello

    We are moving our warehouses of local DAS to a SAN iscsi in common.

    We will have two physical hosts (1 ESX 3.5 and an ESXi 3.5) with two iscsi devices (1 DELL MD3000i and 1 openfiler 2.2 "in the home-built') and two dedicated switches (a 16 ports GBit 1216T one one port 8 Gbps unmanaged Linksys Dlink).

    Both iscsi devices have connections ethernet redundand (Dell has 4 ports on 2 different controllers, openfiler has 2 ports), so I planned to distribute connections on two switches for redundancy.

    each ESX and ESXi physical hosts have 2 ethernet NIC dedicated to iscsi

    My doubts/questions are:

    -is the switch 'Office' of linksys OK for this configuration? Or should I get a second Dlink 1216 T?

    -J' need to have the Dell MD3000i to least performance that we conduct with the local SAS DAS storage.

    Can I activate "frames" switch and Dell MD300i? What ESX and ESXi? and linksys switch (will it work with thaat jumbo mtu)?

    -If I DO NOT activate the Jumbo on openfiles iscsi, will it work with standard MTU even if it is connected to the switches with active Jumbo?

    -should I 'team' toghether both connections ethernet in iscsi on the physical ESX/ESXi hosts?

    an another question I have is:

    -We currently have a LUN iscsi on device openfiler which is accessible using the initiator Microsoft iscsi sw inside a win2k03 virtual machine on the host ESX 3.5. Can I disable initiator Microsoft iscsi inside the virtual machine, log on to this LUN using ESX iscsi sw and have win2k03 to find all the data?

    Thanks in advance

    My computer with two hard drives and 2 starting systems has the car crash in the solid state. When I got the new drive and tried to restore from time capsule, I lost some data. How can I see what backups are on the time capsule? My laptop is also saved to the time capsule. Everything is in 'Data' when I look through the Airport utility. I think that the information that I've lost are still there since I was a Capsule 3 to.

    Time Machine backup to a sparsebundle.

    The sparsebundle will use the share name of computer. So, it should be obvious who is your Macbook and that is your Macpro.

    Open the sparsebundle in Finder and keep open the subfolders until you get to the backup of each separate hard drive...

    You has of course set the exclusion in Time Machine?

    By default, Time Machine will exclude your second drive unless you have included it. Did you?

    Once you get to this level during the backup, you can do a full restore manually whenever you want.

  • How I find myself with two passwords to iCloud for the same account?

    How I find myself with two passwords to iCloud for the same account?

    For security reasons, I only use iCloud for Contacts and "find my iPhone".

    Several months ago Apple forced me to change my password to iCloud.  So I did this.   In the last months, I used successfully the new password to 10 or 12 times when asked without problem.

    However, I received a notification of a software update for my Apple Watch. I did the update without problem. However, after completing the update my iPhone asked me to connect to my iCloud account. When I did this, she rejected my password. I made 4 attempts typing very slowly and with care for you sure I did it right.

    Then, operating under a hunch, I decided to enter my old password to iCloud. It worked?  I'm confused about this, any ideas would be appreciated.

    I had a similar problem last year. I had to call Apple. Contact is a bottom of this page.

  • Using a remote control or the remote with two Apple TV app?

    1 can a remote AppleTV, is the most recent or a last generation we use with two different AppleTV (one is the most recent and is the older generation)?

    2. an iPhone Remote APP can be used with two different Apple TV?

    Thank you.

    1 not easily. There is no way to select the device to control, you end up control both. You could get a programmable remote control and lead to control different devices, but this would require a deception.

    2. no doubt. The Remote app offers a grid of all ATVS, he knows, and you choose the one to control. It has the advantage of a keyboard for searches, passwords, etc. Do you need a remote pair with each ATV.
