SanEd consulting

Company profile

SanEd consulting is an IT training company which initiated its services in 2005 primarily as Sun Microsystem's authorised training provider. Our training portfolio was Solaris and Java focused. Later on we upgraded our portfolio and included authorisations from Veritas / Symantec and Oracle after aquisition of Sun. 

As the global IT market is rapidly changing and developing we must have accepted its needs and trends. Thus, beginning of 2014 we decided to "refurbish" our services and included new, young and perspective partners and together prepared number of interesting trainings you can find in our catalogue.

We are looking forward to successful cooperation with you.

Description

The GL645 is an in-depth course that focuses on two key areas, Linux advanced storage administration and high availability (HA) clustering. Storage is integral to many HA clusters so as to make use of clustered storage technologies to enable active/active configurations.

Over the course of many in-depth lab exercises each student will assemble a realistic three-node Linux cluster utilizing best practices. Each node has three network interfaces and each student's cluster has its own dedicated VLAN.

The class contains an LIO storage array for shared LUNs among the nodes. This enables students to perform very real world tasks in a real world setting, including multipathing, redundant ring cluster communication, quorum disk, and last man standing cluster scenarios. Course topics include: iSCSI, GlusterFS, UDEV, Device Mapper and Multipathing, Cluster LVM, Global File System v2, Corosync, Red Hat Cluster Manager, Fencing, and Cluster Resource Management. 

The unprecedented real world nature of this class requires a classroom configuration that would be daunting (but not impossible) to put together in a physical classroom. The Guru Labs online classroom solution, RLABS, instantly and easily deploys a classroom with the exact configuration needed. Students will be able to focus on the course topics rather than configuration settings outside the scope of the course.
