Poor Computer Performance due to Windows Power Management Settings

In an effort to be more “Green” you will often find that your shiny new computer, laptop or server have Power Management already set to “Balanced” or “Power Saver”.  This can be very useful for cutting your energy bills and saving the planet but sometimes you just get the need for speed.

It’s easy to check your current “Power Plan” in Microsoft Windows Vista, 7, Server 2008 or Server 2008 R2.  Simply click on the Windows Start Menu or Orb if you are using the Aero theme and then select “Control Panel”.  Once in “Control Panel” you can either find it under it’s category “Hardware and Sound” then “Power Options” or if you are in classic control panel mode then you will just need to click “Power Options”.

Once in Power Options you will usually only be presented with three options to choose from, most will find “High Performance” the best option if they want to avoid the occasional slowdowns that power management can introduce.  You will also find that on a laptop the screen brightness is usually increased in this mode and the laptop is not going to keep going to sleep if you walk away from your desk for a few minutes.

If you favour a nice balance between the two then your next best option is “Balanced”.

The “Power Saver” Plan which is the third option is really just for laptop users in my opinion, it’s great for a long flight or train ride where you just need to get some basic Word Documents typed up or reviewed.

Which Printer Driver – PostScript (PS) or PCL [How About Both!]

Printers are probably the biggest source of problems for most IT Admins.  Paper jams, low ink, leaky toner and streeky printing are just some of the joys you will often face.  Another common issue is slow or incomplete printing, what’s the answer to this equally common user woe?

Well your in luck because this is one thing you may be able to ensure is not an ongoing issue for your users.  Most printer manufacturers (i.e. Xerox, Canon and HP) offer Universal Print Drivers (UPDs) to tackle these very issues.

As a rule of thumb PostScript Drivers are best for printing from Adobe applications such as Acrobat (PDF) and/or other complex documents.  PCL Drivers are usually best for priting basic documents, Microsoft Word Documents (doc, docx) and Excel Spreadsheets (xls) to name a few.

You may find it best to install and share your network printer twice, one instance using the PCL Driver and the other using a Postscript (PS) driver.  You then just need to educate your users which printer instance to select from the printer list according to the document type they are dealing with.

HP ProLiant ML Tower and DL RackMount Server – SNMP RAID and Health Checks

My second post is going to be about SNMP checks that apply to the HP ProLaint ML Tower or DL Rack Server, you need to install/configure the Windows SNMP Service, HP Insight Management Agents and the HP ProLiant Array Configuration Utility before these OIDs will work.

Drive Array Health Status = 1.3.6.1.4.1.232.3.1.3.0
1 = other, 2= ok, 3 = degraded, 4 = failed

CPU Fans = .1.3.6.1.4.1.232.6.2.6.5.0 (Usually only appliacble to ML350 G5 as the ML350 G6 Variant does not have CPU Fans)
1 = other, 2= ok, 3 = degraded, 4 = failed

ECC Memory Errors Reported = .1.3.6.1.4.1.232.6.2.3.3.0
0 = No Errors, 1 = 1 Error, etc

Power Supply Status = .1.3.6.1.4.1.232.6.2.9.1.0
1 = other, 2= ok, 3 = degraded, 4 = failed

System Fans = .1.3.6.1.4.1.232.6.2.6.4.0
1 = other, 2= ok, 3 = degraded, 4 = failed

System Temperature = .1.3.6.1.4.1.232.6.2.6.1.0
1 = other, 2= ok, 3 = degraded, 4 = failed

HP ML110 G5 – SNMP RAID Checks

My first post is going to be about SNMP for the HP ML110 G5 Server, you need to install/configure the Windows SNMP Service and the HP Storage Manager before these OIDs will work.

ML110 G5 – Controller Status = 1.3.6.1.4.1.795.14.1.201.1.1.15.1

Status Codes: 1 = other, 2 = unknown, 3 = ok, 4 = non-critical, 5 = critical, 6 = nonrecoverable

ML110 G5 – Logical Drive Status (Array 1) = 1.3.6.1.4.1.795.14.1.400.1.1.11.1

Status Codes: 1 = other, 2 = unknown, 3 = ok, 4 = non-critical, 5 = critical, 6 = nonrecoverable

ML110 G5 – Logical Drive Status (Array 2) = 1.3.6.1.4.1.795.14.1.400.1.1.11.2

Status Codes: 1 = other, 2 = unknown, 3 = ok, 4 = non-critical, 5 = critical, 6 = nonrecoverable

ML110 G5 – Array Type (Array 1) = 1.3.6.1.4.1.795.14.1.1000.1.1.4.1

Status Codes: 1 = unknown, 2 = other, 3 = raid 0, 4 = raid 1, 10 = raid 10

ML110 G5 – Array Type (Array 2) = 1.3.6.1.4.1.795.14.1.1000.1.1.4.2

Status Codes: 1 = unknown, 2 = other, 3 = raid 0, 4 = raid 1, 10 = raid 10

Hope you find my first post helpful.
