Network Setup for 10g RAC

We are planning a 2 node RAC cluster with nodes in two room on a single site. The shared storage will be on a SAN which is replicated/mirrored (via the SAN) to a second SAN in the second room.
Setup
room A :- Node A SAN A
room B :- Node B SAN A
Room B :- mirrored copy of Data on SAN B
(both SAN and Host are capable of connecting to each other through SAN infrastructure)
My question /issue is around the IP network
The plan is for both node A and Node B to have 3 or 4 network connections
1 - Public Net
2 - Backup Net
3 - Private Net
4 - VIP addr - on the Public Net interface
My question s are
1 Do the Public Nets for both Nodes have to be on the same Vlan(subnet) or can they be on different Vlans (subnets)
eg
room A Public Net = a.b.1.0/24 (say gateway is a.b.1.1)
room A Host A public IP = a.b.1.20
room A Host A VIP = a.b.1.21
and
room B public Net = a.b.2.0/24
room B Host B public IP = a.b.2.20
room B Host B VIP = a.b.2.21
assume that there are other host on both networks
Will this work ??
How does the RAC nodes load balance across both nodes ? and are the VIP addrs used to achieve load balancing ??
Second question
While I can connect both room via a private network without routing (via dedicated fibre to two dedicated private net switches. I could save $$ by using a private vlan routed to each room Say a /29 network ( a.b.3.0/29)
Can I connect the private nets via a routed vlan ?

The public IP's all have to be on the same subnet.
Ie, the first 3 sets of number for the IP address
must be the same for the public and virtual IP's.
There are no options in that.Not necessarily, but probably most often correct. If the subnet mask is something other than 255.255.255.0, then the statement above may not hold and/or may not be sufficient. The public IPs and VIPs all must share the same subnet, that much is always correct. What constitutes the same subnet may vary based on the subnet mask used in your network.
For example, if the subnet mask is 255.255.254.0, then 172.16.172.4 and 172.16.173.12 are on the same subnet. Conversely, if the subnet mask is 255.255.255.128, then 172.16.4.2 and 172.16.4.210 are NOT on the same subnet. If you're not sure, consult a network admin--there are also plenty of online tutorials regarding subnet masks and how they work.

Raw Storage device for 10g RAC

Hi
What would be economical & of good quality RAW storage device for 10g RAC setup
Thanks
JIL

Sorry, but what do you mean shared networK?
Yes you need to ensure 2+ server hosts can access the storage array, but if you array can handle multiple direct connections then this is perfectly acceptable for RAC - this is Direct Attached Storage DAS.
Your original post made me think of NAS which may not be what you were meaning, but is how I read network device - NAS, NFS kinda thing - which is NOT a requirement for RAC.

NIC ROUTER requirement for 10g RAC database

I need to know what hardware to order in setting up an 10g RAC database without a single-point-of-failure. My question centers on the networks. If each server has one NIC for the public interface and one NIC for the private interconnect, aren't the routers these NICs are attached to a single point of failure? If each server has two NICs bonded together for the public interface and two NICs bonded together for the private interconnect, does each NIC attach to a different router?

is RDMA and infiband ar same??Infiniband is a switched fabric layer for high speed communication. RDMA is a protocol for "+remote direct memory access+".
Infiniband supports the Internet Protocol suite over Infiniband, or IPoIB. It also supports RDMA over Infiniband.
so do we need only infiband SDR / QDR switch to set infiband OR what else??You need an Infiniband switch - Cisco and Voltaire are two companies that supply this type of hardware. The latter is used by Oracle in its Exadata database machines. Unsure about Cisco's commitment to Infiniband switches as they have discontinued their Infiniband switches with integrated fibre channel gateways. A sore point with us after we bought into this technology about 2 years ago, in part on their very own recommendations - and now own very expensive, somewhat buggy and totally unsupported hardware. Seems like the new Cisco California servers are GigE and not Infiniband, which perhaps explain this (flawed) decision of theirs...
For each cluster node, you need an Infiniband PCI card (typically has 2 ports). If you are going to use bonding, you will need a pair of Infiniband cables per server. Also remember to get spares - both PCI cards and cables.
If you want redundancy at the switch, you need to get yourself 2 Infiniband switches.
But if you're planning to invest this into a RAC cluster, then surely you should also invest money in RAC licensing and support - and with that gain access to very useful documentation like the RAC Starter Kit and so on.

Linux Cluster File System partitions for 10g RAC

Hi Friends,
I planned to install 2 Node Oracle 10g RAC on RHEL and I planned to use Linux File system itself for OCR,Voting Disk and datafiles (no OCFS2/RAW/ASM)
I am having SAN storage.
I would like to know how do i create shared/cluster partitions for OCR,Voting Disk and Datafiles (common storage on SAN).
Do i need to install any Linux cluster file system for creating these shared partitions (as we have sun cluster in solaris)?
If so let me know what versions are supported and provide the necessary Note / Link
Regards,
DB

Info on patches for 10g rac

Hi
I am installing oracle 10g rac release 2 on RHEL 64 bit.
How can I know are there any patches to be applied for that.
Thanks

Run runcluvfy.sh from <CRS_Clusterware>/cluvfy (the location where you uncompressed the CRS binaries)...this will let you know if there are any missing patches.

Client requirment for 10g RAC

Hi,
We are planning to deploy Oracle 10g RAC on itanium Cluster. What is the Client and its version requirement to take full advantage of 10g RAC load balancing/fail over ?
Shanmu
India.

If you want a realistic setup, then you need 3 physical PC's. VM ware installation is too easy, and you dont run into many of the issues you are likely to run into with physical computers. I recommend 3 old PC's with a KVM switch, with Openfiler as the previous post suggested. Put Linux on the cluster nodes, it is free and you dont need much horsepower to run it.

What would be the best network setup for me?

I am planning a network system for my medical practise. The network will comprise a Macbook Pro(myself) , an Imac(receptionist) and a Macbook for occassional admin use.
I need some advice as to the best way to store the shared data. I will be using Filemaker Pro and will be storing patient appointments, demographics as well as clinical info, visit notes and investigations.
I am considering 3 possible setups
Have shared database on the Imac, backed up by a 500 gigabyte hard disk, or possibly a time capsule, using Time machine.
Have an ethernet hard disk for storage, but then I probably would need to have a different backup system.
Use a mac mini as a file server.
Or use an altogether different setup.
I would appreciate suggestions.
Thank you
ajdk

Hi ajdk-
Then it comes down to your morals and how carefully you want or need to protect patient confidentiality. Your basic network concept should work.
As a start, storing any patient data with regular business data and emails is asking for a security breach.
Make sure to back up your back ups and store said backup securely in a media-rated fire proof vault.

Network Setup for a 1232AG config with multiple AP's

I'm looking to deploy a temporary outdoor network using 1232AG radios, with only one radio connected to Ethernet & Internet. All the other radios will have a A radio connection to the parent. And their
G radios will advertise for Client Access. Ultimately I'd also like to have the local ethernets active on each of the remote Radios, so that a switch could be setup for people who don't have Wireless.
So the questions, Is this type of setup even possible? If I use the A radios for back haul, and the G radio for Client Access, does the Ethernet get disabled?
What station-role in the network should each of the radios play. Ultimately I believe we could have different SSID's and IP Subnets for each AP, but if we kept them all the same, can we make this one big Bridge? So that someone can Roam between AP's. Granted I don't have the funds for Wireless Lan Controller. Sugestions?

So what you are trying to do is have some sort of MESH outdoor wireless, but using the 1232AG? Don't think you can do this by using the bridge role. You would have to go bridge to bridge and then have an ap connected to one of the bridge to handle users...

How to Network setup for Lazerjet 6P

I have a lazerjet 6P set up in a PC network and it is shared. I can see it from the Mac air but it won't print. What am I missing ? Please step by step as I am somewhat new to MAC ( It is a transition but well worth it !!!!)
Thanks

What you can try is enabling Windows SMB sharing on the Mac. On the Mac Log into your Windows computer to view something that is shared on the Windows PC, like a hard drive or even just a folder.
Make sure the Windows firewall is turned off (If you are bhind a router you don't need it turn on).
What version of Windows is running on the PC? Win 7, XP, Vista??? Do you have passwords set on the Windows PC?
But in the end I have never gotten my Mac to print to any printer connected directly to a Windows computer. No matter what I try. No matter what permissions I have set on both system. No matter how I connect to the Windows PC over the local network. For me it has never worked and I'm fairly skilled in networking.

Various network setups for media serving and backups

Are there any good sites, blog posts, etc that show different home network configurations with a Time Capsule, external HDs and Macs for handling backups and media serving? Right now I have a simple Setup where my TC backs up my MBP. I also have a couple externals HDs w a lot of music and video that's not in my iTunes library on the MBP, the HD of which is at capacity. I know I want to be able to easily access all of that content on my MBP, AppleTV, iPhone, iPad. I also want to have a good backup solution (possibly even a backup of the backup for redundancy). I just don't know the simplest way to do it and haven't found a good resource to see the alternatives and/or pros/cons of different configurations. Any suggestions would be greatly appreciated!

Network requirements for deploying RAC in VM manager V3 with a RAC template

Now I have two VM servers and installe VM manager on another server.
Each server has only one NIC with one port.
I have deployed single virtual machines successfully on the two VM servers.
Can I deploy RAC with a RAC template with the two VM servers.
How do I need to do with the network?

Yes. Create a new virtual MAC/NIC.
Should you do this?????
NO.
RAC requires a dedicated NIC. Testing... you will be okay but don't expect good performance. You can not do this in production.

What is the minimum required for 10g RAC AIX 5.2L on a SAN

We have the following
2 IBM p550's with AIX 5.2L
Oracle 10g
Hitachi SAN
The questions I have are
1. Does one need any addtional software such as HACMP ?
2. Can one use just RAW 'disks' and not use ASM ?
3. Can one using just the raw 'disks' presented by the SAN with ASM ?
Anything else ?
Thank you,
-pete

Oracle says that from 10g onwards, not need to have any other cluster software since it is providing CRS (cluster ready services) with 10g. However, having HACMP installed would be a good idea. I heard many problem, earliy release of 10g, aboug just using CRS instead of other clustered services.
Well, we are using SHARQ d240 storage, but, didn't required any raw partition, and also not using ASM. Basically, we are in a testing mode.

Best Networking Setup for low CPU use?

Going to be connecting two G4's over a 100-T router. What is the least CPU intensive way to trasnfer files on computer A to computer B?
FTP?
Personal File Sharing?
I need the least CPU intensive out of all the possible options available.
Burning not an option, need to be over the network.

FTP while both machines are connected to a switch that is using Jumbo Frames. Of course, your network cards also have to support it (unlikely in a G4).
Using Jumbo Frames greatly reduces the amount of CPU time due to each packet being able to carry more data (less packets == less processing time). The only issue with JF is that every device inbetween the computers must support the same JF mode.
Since UDP (FTP) is a state-less connection, it is faster.
