It does make a difference, it will only make sense if you require the RAS (Reliability, Availability, and Service) features on x4 or x8 devices and understand the trade-offs for your needs. More details can be explained in the Dell white paper Dell™ PowerEdge™ Servers 2009 - Memory. Also, configuration and layout with details specific to the R710 are ...

The R510 is limited to 128GB of RAM as it has only 8 DIMM slots and only supports two out of three available memory channels on the CPU. The R710 supports up to 192GB (18 DIMM slots) and fully supports all three memory channels per CPU. Even if larger RAM configs are not an issue for you the R710 supports 50% more memory bandwidth because it uses that extra ...

The Express version of iDRAC 7 comes standard on the R720, with an optional upgrade for the Enterprise version.

Do you know sherlock holmes? Read them. One lesson: Eliminate the impossible, then the rest makes sense. My question is: should I install some OS on my Dell EqualLogic? And what exactly do you think you would install on hardware that has firmware that is a dedicated storage array, as also said in the documentation. Accoring to Dell it is a storage ...

This belongs on Superuser, not Serverfault. But regardless, you'd configure the SRX to do a static NAT from it's WAN interface to the internal 192.168.1.3. Then setup a policy to allow traffic across that NAT. I wouldn't allow just any source IP, but at a minimum lock it down to your WAN IP at work. You can follow Juniper's KB here to get you going: ...

I disagree with the other answer here. The best/better practice for ESXi installations is: For standalone ESXi hosts (not in a vSphere cluster): Use local storage to leverage your server's hardware RAID array. If your array controller has the ability to separate logical drives, carve a small volume (4GB->16GB) for ESXi to live on and use the remainder for ...

The PERC 6/i is a dual-port controller; each port has 4 SAS lanes. On the 8x2.5in R710 chassis, that's a one-to-one mapping of front-panel disks to SAS lanes. On the 3.5in chassis, ports 6 and 7 are unused. With a 4-disk array, you could move 2 disks to slots 4 and 5 to split the workload between channels, although there's still the single processor and ...

So I assume you're in an AD Domain, so make sure your client and server show they are using their domain firewall profile. Windows determines it's on a domain by the DNS suffix of it's connection (ipconfig/all "primary dns suffix"). On a new 2008 R2 server I use as a file server, I have file sharing, web server, and DFS enabled, and here's my default ...

its a new machine, why don't you contact dell support?

Yes. You shouldn't leave open U's between servers as it disrupts the engineered airflow of both the server and the rack. If you feel like you need to leave open U's between servers then you should install blanking/filler panels in the open U's. http://search.dell.com/results.aspx?s=bsd&c=us&l=en&cs=04&k=Closeout+Filler+Panel&cat=all

Yes. We have all our R710's fitted one under the other, with no gaps inbetween. We're not running a full rack density (our racks have other things filling the gaps between them like blade chassis etc) but we certainly don't leave any gaps for anything. It's my belief that in modern racks filled with modern servers in a cool environment you shouldn't need to ...

If you have a good RAID controller then why would you try and mess around with software RAID? If you have a good controller, and you disable it, then you obviously won't be able to see the drive because they are physically connected to the RAID controller. They are not like fakeraid on motherboards where you flip a switch and change the mode of the SATA ...

I found I could check the status with MegaCli as ewwhite mentioned: MegaCli64 -PDRbld -ShowProg -PhysDrv [CONTROLLER:DRIVE] -aAll

You can access the DRAC BIOS by using CTRL+E during POST, can set IP address in this BIOS for iDRAC interface. For 4 ports on the integrated NIC you set IP address during OS installation or network interfaces configuration process.

I would search on the official Dell part number. It's not about the OEM for RAM like this. It's about the compatible part numbers (from Dell's perspective). Buy SNPX3R5MC/8G.

Yes, this is definitely supported. As Mike Naylor stated, most modern RAID controllers should be able to do this (even desktop systems that support RAID with an integrated controller on the motherboard support this). The documentation makes no mention of the number of supported disk groups. Limitations are stated in terms of virtual disks, spans, and ...

iDRAC 7 Express comes on R720. To upgrade to Enterprise you purchase a licence then upload the licence to the iDRAC it is not a hardware upgrade. You can do this when you purchase the server or after the fact. This is a change from iDRAC 6 on the R710.

This question is on the borderline of shopping, but I can tell you our experience with those servers. Dell, like any other server vendor, wants your unborn children for upgrades after you've bought a server. My solution was to replace all the RAM in the system with Kingston system-specific memory, which have a lifetime guarantee and is 100% compatible. ...

If you have Dell's OpenManage software installed, you can also use omreport storage vdisk to provide a summary of all virtual disks (which should include rebuild progress). Technically megaCLI isn't considered a "supported" tool by Dell (even though I think it's probably what's being used on the back-end by OMSA), but it's still a VERY useful tool when ...

While there are some iSCSI boot-from-SAN options, your cleanest approach to installing ESXi onto your host servers is to either use local hard disk (single or mirrored pair) or leverage the internal USB or SDHC slots on the server. VMware ESXi installs differently, depending on the media you use. In reality, ESXi only consumes 900 Megabytes of space, so the ...

It has it's own IP-based access control. It can be configured as outlined in this section of the manual. It's not iptables, but it does what you're looking for.

4 disk RAID 10 gives you performance of 2 disks for writes and 4 disks for reads (absolutely best-case scenario). A 7200 rpm HDDs should give 75-100 IOps. What kind of performance do you see? Do you read %util close to 100 in iostat? If the primary load is generated by a database, what makes you think it is going to be mainly sequential? Databases are the ...

So you're going to hate this but I'm willing to bet that you are using either the H200 or H700 raid cards. These aren't really cards so much as some software on the motherboard that interfaces with Windows. They fail to mention that they are completely unsupported in Linux.

If you've replaced the entire server from Dell, then it has to be your RAM - that's the only variable you haven't eliminated. I'm surprised Dell issued you an RMA without forcing you to change the RAM in the first place.

http://support.dell.com/support/edocs/systems/per510/en/HOM/PDF/510en.pdf p114. It's a triple channel system. The part I'm still uncertain on is how they say channel 0 can have two modules while 1 and 2 can only have one. If all 4 per CPU are populated, I'm still not sure if it's a special dual channel mode (combining channels 1 and 2) or a special ...
