Dell PowerEdge R420
Dell PowerEdge R420 servers are robust enterprise-level machines that support a wide range of applications.Thanks to the built-in Integrated Dell Remote Access Controllers (iDRAC), users are able to seamlessly manage several virtual machines remotely, making these servers highly scalable and suited for a very large variety of applications. They are dependable machines that provide adequate redundancies for business applications.

Intel® Xeon® E5-2400 series processors feature enhanced virtualization capabilities (Intel VT-x and VT-d) ensuring maximum efficiency when working with hypervisor applications such as VMWare ESXI. A maximum clock speed of 3.33 Ghz allows for high performance in single-threaded applications. Up to 32 threads allow for highly multi-threaded applications. Equipped with Intel SpeedStep technology, these processors will dynamically adjust their power usage and reduce their clock speed when the load is light.
DDR3 memory means these servers meet the needs of modern applications that can benefit from increases in memory speed. The flexibility offered by 12 slots that can be populated with up to 32GB PC3 DIMMs allows these servers to operate effectively even when a large amount of memory is required.
In addition to the wide range of capacities that can be installed, these servers support ECC (Error-correcting code) memory. This enables operation in mission-critical environments where consistent system uptime is required and data integrity must be preserved. Here at TechMikeNY, we recommend that all mission-critical systems that require a high uptime be configured with ECC ram.
This server is compatible with Dell PERC storage controllers, offering hardware RAID functionality. This ensures that if a disk failure occurs, there is no loss of data or interruption to your operation. These controllers support up to 1GB cache configurations, which in turn allow the controller to speed up reading and writing to your disk array. The cache is protected by a battery, which allows the controller to retain data that hasn’t yet been written to the disk, in the event of a sudden power loss. With support for up to 4 x 3.5" or 8 x 2.5" drives in hot-plug bays connected to the storage controller, you will be able to expand your storage as needed while retaining a level of redundancy.
With dual gigabit network ports, this server is able to handle the networking needs of the most demanding business environments. These ports are capable of NIC-teaming, which allows a server to bolster the bandwidth available between it and the network by combining multiple ports in a single link for a faster transfer speed.
A dedicated port for the remote management capabilities available through Dell’s iDRAC 7 Enterprise means that you won’t need to share the bandwidth of your server with management operations. This also allows you to separate the management network completely, thereby enabling you to adequately manage your server even when the available bandwidth is being saturated by the network load.
With support for redundant hot-plug power supplies, you won’t have to worry about data loss due to a power supply failing. These power supplies can be connected to two separate power lines so as to ensure that a power outage doesn’t interrupt server operations. If one power supply is still connected, the other can be swapped out without shutting the server down, ensuring a power supply failure does not cause an outage.
