Networks 101 – Configuring subnets and VLANs for basic network isolation

Over the last week or so I have spent some time configuring some new networking gear for one of eShare’s numerous internal SharePoint farms and I thought I’d share a few of the lessons I’ve learned along the way.

My task seemed pretty straightforward: implement a couple of load balanced firewalls along with 3 isolated network segments. This is quite a common scenario for us as we deal with a lot of security sensitive clients who aren’t big fans of back end servers sharing a subnet with those that are public facing. Indeed, there are few reasons not to implement a segmented network such as this as it provides a form of defence in depth should your perimeter servers be compromised. Continue reading

Determining NUMA node boundaries for modern CPUs

Last Wednesday I had the pleasure of presenting at the East Anglia SharePoint user group (SUGUK). The user group is organised by Randy Perkins and Peter Baddeley who are both very friendly, knowledgeable SharePoint guys. Whilst my session aimed to provide some general guidance on SharePoint administration (I’m presenting a similar deck at SharePoint Saturday), the subject of this blog is a topic covered during the evenings first session: “SharePoint 2010 Virtualisation“, presented by John Timney (MVP). To be more specific, this post discusses NUMA node boundaries in the context of virtualising SharePoint and hopefully raises some questions around whether the MS documentation should perhaps be updated to include guidance for larger multi-core processors (i.e. more than 4 cores).

Bitesize Video Overview: Host-named Site Collections in SharePoint 2010

Today I published a post on SP365 which attempts to explain host-named site collections to the uninitiated in the form of a bitesize video overview​.​

Host-named site collections are a key part of SharePoint 2010’s multi tenant support and offer a huge amount of scalability. They provide support for multiple root named URLs (vanity URLs) and in many cases are a valid alternative to creating additional Web applications.

If you have any feedback or suggestions, feel free to add a comment.

Content DB sizing support in SharePoint 2010 SP1: the 50,000 ft view

11/07/2011 Update:I have had some feedback around this article that made me realise that I inadvertently​ gave RBS a bit of a bashing. It’s a useful technology that – used in the right scenarios – can significantly improve maintainability and scalability. The main point of the RBS section was to debunk the myth that RBS provides a means of bypassing the [current] data sizing boundaries that Microsoft provide.

The recent post from the SharePoint Product Team blog on Data Storage Changes for SharePoint 2010 has caused quite a stir. Continue reading

How I passed SharePoint 2010 exam 70-667 (Part 3 of 4)

​​​Looking for the downloadable PDF? Click here​.

As I explained in the introduction to part one, the blog is published retrospectively and (aside from correcting the odd typo) I haven’t made any changes to my original revision notes so as to ensure I don’t violate the Microsoft NDA that all exam candidates must sign. As such, you might notice the odd error or missing section (in particular you will notice that there are very few notes on Sandboxed Solutions). This is deliberate, although I would appreciate a comment if you notice any glaring mistakes so as to prevent misinformation. Continue reading
