Efficient High-Available LoadBalanced Cluster On CentOS 5.3 (Direct Routing Method)
This article explains how to set up an LVS cluster of load balanced virtual
servers with Heartbeat and Ldirectord On CentOS 5.3.The load balancer sits
between the user and two (or more) backend Apache/IIS web servers that hold the
same content. Not only does the load balancer distribute the requests to the two
backend Apache/IIS servers, it also checks the health of the backend servers. If
one of them is down, all requests will automatically be redirected to the
remaining backend server. Read more: |

High-Availability Storage With GlusterFS On Ubuntu 9.10 - Automatic File Replication (Mirror) Across Two Storage Servers
This tutorial shows how to set up a high-availability storage with two storage servers (Ubuntu 9.10) that use GlusterFS.
Each storage server will be a mirror of the other storage server, and
files will be replicated automatically across both storage servers. The
client system (Ubuntu 9.10 as well) will be able to access the storage
as if it was a local filesystem. GlusterFS is a clustered file-system
capable of scaling to several peta-bytes. It aggregates various storage
bricks over Infiniband RDMA or TCP/IP interconnect into one large
parallel network file system. Storage bricks can be made of any
commodity hardware such as x86_64 servers with SATA-II RAID and
Infiniband HBA. Read more: |

How To Enable Networking In Xen Guests On Hetzner's New EQ Servers (Debian Lenny)
This tutorial shows how you can enable networking in Xen guests (domU) on Hetzner's new EQ servers.
With the new EQ servers, you can get up to three additional IPs that
are in the same subnet as the server's main IP. The problem is that
these additional IPs are bound to the MAC address of the host system
(dom0) - Hetzner's routers will dump IP packets if they come from an
unknown MAC address. This means we cannot use Xen's bridged mode, but
must switch to Xen's routed mode where the host system (dom0) acts as
the gateway for the guests. Read more: |
