Dell Poweredge Server Lineage

With the 10th Generation of the Dell Poweredge Servers out, the topic has come up about the Dell Poweredge Server family tree. There is really limited information even from Dell on the history of the Poweredge Server. I was hoping there would be a handy dandy document of evolution of servers complete with model number, years in production and all specs. Sadly, nothing comes that easy! I was able to find a list of model numbers from some helpful gentleman on Wikipedia so that was a start. Here is a list (not perfect but close) of all the Dell Poweredge Servers and the year of production.

As the years progressed, so did form factors. Towers are what started it all. Typically those older servers came in the 7U form factor and weighed about as much as a new Hummer.

Around the late 90s as more models came out they were all towers, but smaller sized towers. For example the Dell Poweredge 1300 would be say a mini tower by today’s standards and the Dell Poweredge 6350 would be a beastly 7U tower or the Hummer!

Right around the year 2001, servers became lighter in weight and the Dell Poweredge 1550 was welcomed with open arms to all techs that were suffering from sore backs.

In 2009, Dell exploded with many models of towers and rack mount servers along with a series of servers that featured the AMD Operton processors.

The “C Series” of Dell Poweredge Servers are starting to come out as of 2010.

If anyone has any other information, feel free to add or comment with correct information. I hope this is helpful to those that need it or to those that are just curious.

Velocity Tech Solutions - How to replace a Dell PowerEdge 2850 backplane

Dell PERC Raid Controllers: What are they and what are the differences between each?

By Kay Winchell, CIO, Velocity Tech Solutions,

“PERC” is a term used to describe the Dell PowerEdge Raid Controller family. PERC controllers are the interface between the operation system read/write instructions on the hard drives. These cards (for attaching storage to a server) or kits (for raid arrays internal to the server) have series levels from Perc2 to Perc6 and have been followed by the new H series. The various controllers have features that are mostly differentiated by type of connector, (PCI, PCI-E, SAS) raid levels supported, (Raid, 0,1,5,6,ect), the maximum level of hard drives supported, and whether they are internal kits or external cards.
The chart below describes first the internal (Integrated) Raid kits and secondly the external Raid Cards, the machines they are compatible with and the most common features known to us. Dell does have multiple part numbers for items that perform the same function, so we have not included the actual SKUs for the items. I have started with Perc 3 because the older Perc 2 cards are fairly rare now. Also, I have excluded some of the more uncommon raid controllers or controllers that are made for just one machine. The list below is not complete, please feel free to add or correct as necessary. Contact me if you have questions about what raid controller goes into your PowerEdge server.
The internal kits are usually composed of the Raid Key, the Raid Battery and the Raid (Cache) Memory dimm in the older servers. The key is typically installed on the mainboard of the server, while the battery and memory are usually found on the riser card. The newer servers usually just have an internal card that has the cache memory and a battery mounted on it.
The external card plugs into an expansion slot in the back of the machine and cables to a storage unit such as the Powervault or newer MD Series Enclosures or in some cases to a tape back up unit.

“I just got my server and it doesn’t work”

One of the most common questions we get here at Velocity Tech Solutions “I just got my server and it doesn’t work” or “my server just stopped working what do I do?” After that question there are typically a series of questions (with a little panic in the voice) “will I lose my raid”? “Is it the motherboard?” “I’m totally down, what am I going to do?”

There may be no need to panic it could be something simple.

Often times in shipping the server will take a bit of a beating. Many of them weigh 50 to 100lbs and the delivery drivers seem to loathe those poor packages more than the 3 oz boxes that can fit in their hands. There is also the reality that the delivery trucks don’t ride as smooth has a Cadillac. As a result of the server taking a rough ride both in the vehicle and via the loading process, the vibration of the rough ride can result in the memory, the processor, the riser or the controller card coming lose. Reseat each part in the server. Make sure each part is clipped in and secure.

The same can be true of a server that has been running constantly for a very long time. Servers pack a lot of power and over time the vibration can jolt some of the parts loose.

This may not be the only answer, but this is a starting point.

You can always call me, VelocityAnne at 888-784-2088 with any questions, anytime!
