No, I’m actually not talking about the crazy SNL skit and follow-up with Mark Walhberg!

No, I’m talking about Exchange and its IO going through the roof when you use Entourage for the Mac in a typical Exchange environment.

Microsoft has a KB329067 Article which relates to this issue with some ‘guidance’ on how to correct it, but exactly how far you take it is another matter.

Information about performance issues that occur when you use POP3, IMAP, or WebDAV clients, such as Entourage, after you move mailboxes in Exchange Server 2003 or in Exchange 2000 Server

Basically, what you’ll get from this article is this:

1. Start Registry Editor.

2. Locate and then click the following registry key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeWEB\DAV

Note By default, the DAV key is not in the registry. You will have to create it yourself.

3. On the Edit menu, click Add Value, and then add the following registry value:

Value name: MaximumResponseSizeInBytes
Data type: REG_DWORD
Radix: Decimal
Value data: value

For example, if you decide to increase this value to 500 megabytes (MB), use the following calculation:

1024 * 1024 * 500 = 524288000 (Decimal) = 1F400000 (Hexadecimal)

Enter the results of this calculation in the Value data field. In this example, you would enter 524288000 (Decimal) or1F400000 (Hexadecimal). Remember that the configurable range for this registry key is 1 MB to 1 gigabyte (GB). Better results occur if customers set it to a value of 500 MB or a higher value, such as 800 MB.
NoteWe recommend that you set the value back to the default value or to a lower value after the content conversion issue subsides in your organization. The default value of this registry key is 128 MB. We also recommend that you set correct messages limits and mailbox size limits on your Exchange server to prevent performance issues.

4. Exit Registry Editor.

I can only read this particular KB article so much before I say “Hmm, but what actually works?”

Here is a solution which is tried, true, and used and tends to work most of the time.

Modify this Key to this value:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeWEB\DAV

Value name: MaximumResponseSizeInBytes

Decimal: 838860800

What this does is set it to 800MB, as opposed to the ‘referenced’ 500MB example.

In a majority of all circumstances this will take considerable strain off of both your Exchange server as well as your underlying storage.   The end result is, Marky Mark and the Entourage Bunch won’t cause Exchange to Spike and cause severe latency issues for your users.

I think that calls for a definite win situation!

Kind of like how Andy wins in this situation…!

Hey everybody! A few updates which will directly impact you that you should know about!

First of all, I’ve updated the Free Testing Archive to age old invalid certs and include new certs – So check it out!

Next of all, we’re getting closer to the availability of the NS1-501 SAN Exam from NetApp.  Prometric has the details published just not available to schedule a test yet.  That should change in the next week or so.   This is an entirely new exam so any old ‘test data’ which one has for it, likely won’t be valid anymore.    I’ll need to rewrite the study guide I wrote for the original version.

Next, welcome the first in a series of .NET 3.5 beta exams!

71-563: Pro: Design & Dev Windows Apps Using MS.NET Framework 3.5 – October 13, 2008 – October 30, 2008 (Code: DW897)

We have a number of folks to thank for this Exam! I’d like to make sure you know about the Beta Exam Blog where this was posted, as well as GerryO who posted about this :)

(This is also posted to the Free Testing Archive!)

Anyone who remembers my Second Chance Promotion post earlier in August (Second Shot)

Well, thanks to the MSL Community and GerryO again for this:

But wait, what else is new? There’s another new NetApp exam coming :)

It’s not visible yet, but I have a feeling it’ll be here soon.

NS1-501 NCIE-SAN from NetApp!

This exam was in beta last year, and I imagine the stakes have changed and the test has gotten harder! Last time I took it (Last August) I got 100% (booyah!)

So, Look forward to seeing that come out somewhere in the next few weeks!

I took these two beta exams this past week, and let me start off first by saying, Wow! These are quite possibly some of the most polished exams I’ve ever seen!

The content was clear and concise, the questions were spot-on, and the delivery was amazing! I had no comments to offer other than "Wow, great exam" (I’m paraphrasing!:))

However, going past that, we get into the depths of the Post-Mortem.

071-451 was an excellent exam, the questions were very focused on your ability to Design, Optimize, and continually work on making sure that your data was delivered in a consistent fashion while also validating for performance and a number of other figures.   If you’re a day-in-day-out DBA who looks at improving your SQL Data, then this is the exam for you.

071-450 was also an excellent exam, the questions were very focused on your ability to actually manage your data, be it in clusters, clustered and non-clustered indexes, mirrors and especially the ability to back up your data.   If you happen to wear the hat of managing the databases and spending less time writing queries, this exam is spot-on and will be a breath of fresh air to you.

In all, I have nothing special to offer you outside of "If you know you’re stuff, you’ll be ready for these exams"

However, I did encounter something disturbing.   While taking 071-450 an exam focused on "Designing, Optimizing, and Maintaining" a database environment, I encountered a considerable volume of "How do I back this up" type of question, equally followed by a series of "How do I restore and get back into operation" type of questions.

Which leaves me to think, it’s 2008 already, is this seriously still a question?    I hear it in the field all the time as well, and I’m seriously disturbed.    The amount of data we have is growing, our windows – shrinking.   There are options and opportunities to ensure you have a quick, efficient and effective backup, restore and operational window.   When it’s still a question on the table – especially in an emerging product like SQL 2008, I have to seriously ask, Are we taking steps backwards instead of adopting the innovations available to us over the years?

Yes I work for NetApp, and yes I’ve seen the light offered by amazing solutions like SnapManager for SQL, and SnapManager for Oracle, and a series of other products to protect everything important within every small, medium and enterprise business.    And to be honest, this isn’t rocket science (Rocket Science is FAR easier) especially when you compare it to the number of "backup" options available to "try" to protect your SQL environment only to leave you scratching your head and still unsure about your availability and recoverability.  

And to be honest, this isn’t a commercial, whereas in reality that test was a wake-up call of "WTF is going on?!" I don’t want to be in this same position 2 years from now in 2010, and 12 years from now in 2020 and having it still be a question on the table of "How do we protect and recover our data?"   

You long-time and short-time admins out there, you ever ask the question "Wow, I wish I had an owners manual for my filer".   I hear it time and time again about the sheer volume of information available to support the filer, but nothing short, simple and sweet to cover it.
