In this article I will mention the steps to mount an ISCSI target on two ubuntu machines and then cluster it using oracle clustered file system. The newly mounted partition can be used as a centralized storage location in High availability, Failover or load-balancing setup. The step by step howto is provided below, 1) Setup an ISCSI Server using Openfiler and create SAN LUN, and assign the IP 192.168.1.11 to it.
For setting up openfiler based ISCI target, you can refer steps 1 to 8 mentioned in the url pasted below. 2) Setup two servers with Ubuntu 10.10 in it. server1 ==> name: heuristics –> IP 192.168.1.30 server2 ==> name: heuristics2 –> IP 192.168.1.32 3) Install open-iscsi tool in both servers apt-get install open-iscsi open-iscsi-utils /etc/init.d/open-iscsi start 4) List out the ISCSI targets available in both servers. iscsiadm -m discovery -t sendtargets -p 192.168.1.11 In my case the above command produced the following output, root@heuristics# fdisk -l apt-get install ocfs2 ocfs2-tools.
OCFS2 cluster – quick setup guide - Cloudibee's Notes. OCFS2 is a POSIX-compliant shared-disk cluster file system for Linux capable of providing both high performance and high availability. Cluster-aware applications can make use of parallel I/O for higher performance. OCFS2 is mostly used to host Oracle Real application clusters (RAC) database on Linux clusters. The below steps shows how to create ocfs2 filesystem on top a multipath’d SAN lun and mount it on Linux clusters. Identify the nodes that will be part of your cluster.Export/Zone the LUNs on the SAN end and check whether they are accessible on all the hosts of the cluster. (fdisk -l or multipath -ll)If you need multipathing, configure multipath and the multipathing policy based on your requirement.
For Linux multipath setup, refer Redhat’s multipath guide. Create OCFS2 configuration file (/etc/ocfs2/cluster.conf) on all the cluster nodes. Using OCFS2, A Clustering File System. Get a grip on the next-gen Oracle Cluster File System, an alternative to GFS. Traditionally in Linux, if you wanted to access a file system from more than one machine you would mount it on one machine, and then export it to the others via NFS, CIFS or something similar. This is a stable, mature and well documented procedure, but it does have its downsides.
Performance is not great, there can be locking issues, there are potential security implications and worst of all you have a single point of failure. If your NFS server goes down, all clients immediately lose access. Luckily, there is another way to accomplish this task. Now you have iSCSI and your choice of Open Source clustered file systems available. Another option is OCFS2, which is the next generation of the Oracle Cluster File System. The OCFS2 user space tools are available for a variety of distributions, either directly from Oracle or from the distribution manufacturer. O2CB_ENABLED=true Now mount your partition on each machine. Using ATA Over Ethernet (AoE) On Ubuntu 12.04 (Initiator And Target) Version 1.0 Author: Falko Timme Follow me on Twitter Last edited 10/01/2012 This guide explains how you can set up an AoE target and an AoE initiator (client), both running Ubuntu 12.04.
AoE stands for "ATA over Ethernet" and is a storage area network (SAN) protocol which allows AoE initiators to use storage devices on the (remote) AoE target using normal ethernet cabling. "Remote" in this case means "inside the same LAN" because AoE is not routable outside a LAN (this is a major difference compared to iSCSI). To the AoE initiator, the remote storage looks like a normal, locally-attached hard drive. I do not issue any guarantee that this will work for you! 1 Preliminary Note I'm using two Ubuntu 12.04 servers here: server1.example.com (Initiator): IP address 192.168.0.100 server2.example.com (Target): IP address 192.168.0.101 2 Loading The aoe Kernel Module On Both Systems server1/server2: Before we start, we must make sure that the the kernel supports AoE: lsmod | grep aoe modprobe aoe server2: How To Build A Low Cost SAN. Krishna KumarApril 9, 2009 In today's world there is a obvious need of information sharing in every department and network storage can help us to achieve this most growing challenge.
Here in this article we are focusing our concentration to make a San which has following features: Low cost and easily affordableEnsured ScalabilityHigh ReliabilityEasily ManageableHigh PerformanceEnsured SecurityHigh availability 2 Available Options For SAN There are some options available to make a reliable San which is quite complex and expensive. 3 Cost Comparison among AoE, FC & iSCSI Cost Comparison 4 Comparison of AoE vs iSCSI 4.1 These are the following advantages of AoE over iSCSI AoE is cheap and simpler software stack. 4.2 Disadvantages of AoE over iSCSI If you need features such as encryption, routability and user-based access in the storage protocol, iSCSI is a better choice.AoE is not much suitable for critical enterprise applications. 5 Available AoE Targets Features. Use AoE to Build Your Own SAN. When I first heard of the ATA over Ethernet (AoE) protocol, I got excited about the possibilities.
Sending ATA commands directly over an Ethernet physical layer offers tremendous simplicity, flexibility and low overhead that potentially could result in astonishing performance. As the rumors of official acceptance into the Linux kernel grew louder, I waited with bated breath. I believed this would be game-changing for the storage market. When it made its way into the official kernel tree and 2.6.11 was released in early 2005 with built-in AoE support, it was all I could do not to stand up and cheer.
The obvious question is what possibly could warrant such excitement? We already had Fibre Channel and iSCSI. Essentially, AoE is an open-standards-based protocol that allows direct network access to disk drives by client hosts. Now, imagine that you could build a box designed specifically to be an AoE target and export your arrays as block devices over your Ethernet network. Construire un SAN LowCost avec le protocole AoE (ATA Over Ethernet) Merci de votre visite. Vous semblez être nouveau ici, peut être seriez vous intéressé de souscrire à mon flux RSS.
Aujourd’hui lorsque, vous souhaitez mettre en oeuvre un SAN, vous avez généralement le choix entre iSCSI, Fiber Channel, ou beaucoup plus rarement NBD (Network Bloc Device) ou eNBD (ehanced Nework Bloc Device). Mais connaissez vous l’AoE ou ATA Over Ethernet ? AoE est un protocole développer par Brantley Coile communicant sur la couche MAC afin de transférer des informations ou des données entre périphérique de stockage ATA ou IDE.
L’avantage majeur sur les technologies iSCSI et Fiber channel, qui soit dit en passant sont les plus répandues, c’est le coût: Les chiffres parlent d’eux même… Autre avantage, AoE est un protocole qui fonctionne au niveau MAC et n’utilise pas le protocole Tcp/Ip comme le iSCSI, NBD ou eNBD. Coté matériel, le protocole AoE fonctionne sur des cartes réseaux et des Switchs standards. Malgré cela, AoE présente quelques défauts par rapport à iSCSI. Puis. AoE: L’alternative SAN crédible Horoa – La voie est libre. Les besoins en stockage des entreprises sont de plus en plus importants! Les acteurs sont nombreux sur ce marché mais les technologies, elles, se comptent sur les doigts d’une main.
Je vous propose de nous intéresser à une technologie de plus en plus appréciée, hier encore considérée en marge: ATA over Ethernet. L’augmentation générale de la capacité des machines et d’internet, les besoins changeants, la virtualisation des systèmes x86… tout ça n’est pas fait pour aider les admins à construire, déployer et maintenir une architecture de stockage en toute sérénité. Il existe une multitude de solutions, proposées par des acteurs du marché plus ou moins convaincants, mais quasiment toutes sont basées sur les deux mêmes technologies: Le Fiber ChannelLe iSCSI Ces technologies ont longtemps été considérées par beacoup, comme LE chemin à suivre, parfois de façon aveugle.
A l’évidence, aucune de ces solutions n’apporte de réponse à l’ensemble des besoins. AoE, wide open. Simple is beautiful. Construire un SAN LowCost avec le protocole AoE (ATA Over Ethernet)
