We are considering adding a SAN. I have two choices right now, the Dell MD3000 and the Dell MD3000i, 15 x 146Gb san drives. Naturally the latest model is more expensive (2x as much), but can someone tell me if the speed difference is considerable to be worth the extra cost? Our DB on Sql Server 2008 r2 is only about 30Gb and not expected to grow much over the next few years. We have […]Continue Reading »
Which hardware gives us better redundancy, performance, and cost efficiency for a large Enterprise Cloud Solution?
We are going to build a Large Enterprise Cloud Solution and would like to know in which configuration we would have a better redundancy/performance and cost efficient. Here are 2 examples which we’re considering as good configurations to grow. Main Hardware: 42U Rack 2x Dell Force10 S4810 2x HP P2000 iSCSi (2x AW595A Controller), 12x 600GB SAS (RAID10) Example 1 for a configuration with many small nodes: 36x HP DL120 G7 (Xeon® E3-1240 @ 3.30GHz), […]Continue Reading »
Seems like a June 6th post by Dell states that the RTM version of Windows Server 2012 should have all the necessary drivers for a Dell G1 1950 -> SAS5 -> md3000 setup. Can anybody who’s tried this verify if it works or not? (And yes I’d love to upgrade this stuff but I don’t think there’s a budget for that.) Asked by tony roth Seeing as it most likely will not be supported by […]Continue Reading »
I have various Dell servers (all 2950’s) I would like to put some SSDs in. I have spoken to Dell on the phone and asked for a quote for 128GB SSDs for 2950’s, they told me they don’t sell them for this server. These all have Perc 6/i’s in them. Can I purchase any SSDs with a SATA II connection, of my liking, and connect this? Or will they be “blocked”, or not work as […]Continue Reading »
I have a Dell 2950 with a Perc 5/i controller inside it. I don’t want to spark a debate about drive types and which is “better” etc etc. Just simply; I would like to put in 2x Cheetah 15.5k SAS drives and mirror them for the OS. I would also like to put in 2x SSDs (exact model is still being debated) and mirror those for the data. Can the Perc 5/i manage multiple RAID […]Continue Reading »
What are the most important aspects to consider when choosing a SAN for a small office virtualization project?
I am in the process of consolidating 6 physical servers running 6 different operating system flavors (don’t ask) into two identical physical servers (Dell PowerEdge 2900), using the free VMware ESXi 4.0 platform. We will install an iSCSI SAN over a 1GbE network, and store all virtual machine images on the SAN. Each physical server would run 3 VMs, and in the case of a physical server failure, we would manually switch over the other […]Continue Reading »
So we just picked up a new PS6100x and I’m wondering if I need to setup the ethernet channels myself or is it automatic? It’s configured in an HA setup; dual controllers connected to redundant cisco switches with a 10GE interconnect. On the controller, I’ve enabled eth0-3, each with it’s own IP 172.16.0.50-53, and a group IP address of 172.16.0.10. Do I need to bond the interfaces on the switch or will the controller take […]Continue Reading »
We have customers infrastructure hosted on physical HP boxes across several racks and finally we are planning to migrate them to Vsphere.Data is stored on NFS SAN.It was suggested to use c-Series Dell servers for hypervisors. In the past I have been involved in projects that used blades for virtualization and using c-Series feels like a unusual choice for me. I am trying to figure out what are the pros and cons of using blades […]Continue Reading »
Is it possible to install a virtual machine under Linux that looks like a Windows machine to IT? [closed]
I’m on a corporate network with a homogeneous Windows setup for all Dell workstations. They use KBOX to manage the workstations. I want to set up my machine to run several VMs under Linux instead, but they’re concerned that this will make them unable to manage the workstation with KBOX, resulting in having to eventually wipe it and install the standard Windows workstation on this machine. Is it possible to set up this Dell workstation […]Continue Reading »
I have a Dell PowerEdge R710 with dual 55xx CPUs. It has 96GB(12x8GB) of ECC DIMMs. In its BIOS, memory is configured for “Advanced ECC”. My question is if my DIMMs are already ECC, does it make sense to enable this “Advanced ECC” mode in BIOS or should I switch to “Optimized”? Dell describes these modes as such: Advanced ECC Mode This mode uses two MCHs and “ties” them together to emulate a 128-bit data […]Continue Reading »
