Virtual SAN: An Ideal Choice for Management Storage

MHoskenBy Martin Hosken

The practice of separating management components onto a dedicated vSphere cluster has become common practice in recent years. However, such a cluster should aim to have no dependencies on the production systems with one of the key requirements being that any type of incident or outage affecting the production system does not affect the management cluster, and likewise any management cluster outage cannot affect the production workload systems.

In the past, providing dedicated out-of-band storage for management-only clusters could be cost-prohibitive. It was necessary to purchase additional independent storage hardware for management clusters that could provide the performance and availability required for I/O-intensive and highly available virtual machines, as well as to provide expensive isolated storage fabric to provide connectivity to the management-only array. VMware Virtual SAN provides a highly performant shared storage platform across the vSphere cluster making it possible to significantly reduce costs whilst maintaining enterprise levels of availability and performance.

This makes Virtual SAN the ideal choice to provide true out-of-band management storage to a dedicated management cluster, making this type of truly independent management environment a viable and affordable option for most medium and large organizations.

This white paper provides a detailed rational and design for utilizing Virtual SAN in a dedicated management environment.

Overcoming Design Challenges with an Enterprise-wide Syslog Solution

MHoskenBy Martin Hosken

I’ve spent a lot of time helping my customers build a proper foundation for a successful implementation of vRealize Log Insight, and I’ve published a white paper that highlights key design challenges on how to overcome them. I’d like to share a brief overview with you here.

VMware vRealize Log Insight gives administrators the ability to consolidate logs, monitor and troubleshoot vSphere and to perform security auditing and compliance testing.

This white paper addresses the design challenges and key design decisions that arise when architecting an enterprise-wide syslog solution with vRealize Log Insight. It focuses on the design aspects of syslog in a vSphere environment and provides sample reference architectures to aid your design work and provide ideas about strategies for your own projects.

With every ESXi host in the data center generating approximately 250 MB of log file data a day, the need to centrally manage this data for proactive health monitoring, troubleshooting issues and performing security audits is something that many organizations continue to face every day.

Note: A symlink is a type of file that contains a reference to another file in the form of an absolute or relative path.

VMware vRealize Log Insight is a scalable and secure solution that includes a syslog server, log consolidation tool and log analysis tool that works for any type of device that can send syslog data and not only the vSphere infrastructure.

As with any successful implementation project, the need to plan and design a solution that meets all the requirements set out by the business is key in ensuring success, and developing a design that is scalable, resilient and secure is fundamental to achieving this. And this includes keeping in mind the requirements of your business leaders, system administrators and security auditors as well.
