Linux SUSE servers clustering and DMZ

Linux SUSE servers clustering and DMZ

Hello,

To answer Your question with relevant details, we will want to specify a certain criteria, or standards, for a serious enterprise operating system, all in relation to SUSE Linux.

File system support – SLES has a solid file system support: ext3, ReiserFS, XFS, and OCFS2.  Now, XFS is crucial
to note, when we are talking about handling large storage, journaling, and scalability.

Then, there is support for OCFS2(Oracle cluster File System2), open source clustering file system with very high performance.

Good failover/HA clustering support

SLES has a rich set of both graphical user interface and command line interface tools for management and configuration.

For additional notes, I will refer to Heartbeat here:

Furthermore,

Automated installation(AutoYast is a powerful tool worth mentioning), package management(also, very capable YaST tool comes in handy, and can operate in text mode
as well), provisioning.

ISV(independent software vendor) applications certification and application portfolio.

Oracle Database support(with Real Application Cluster included)

XEN and KVM virtualization.

Openswan, that is – IPsec support implementation.

POSIX compliance.

So when it comes to Linux, and enterprise environment, these important underlined characteristics make Suse Linux Server a stable, secure, and cost-effective operating system, as it meets crucial demands.

On the top of all that – Novell(SLES), along with Red Hat(RHEL), has a leading position on linux server market.
