Parameter

Description

 

 

Datagrams Forwarded

The number of input datagrams for which this entity was not their final IP

 

destination, as a result of which an attempt was made to find a route to

 

forward them to that final destination.

Reassembly Required

The number of IP fragments received which needed to be reassembled at

 

this entity.

Reassembly Failures

The number of failures detected by the IP re-assembly algorithm (for

 

whatever reason: timed out, errors, etc.).

Datagrams Failing

The number of datagrams that have been discarded because they needed

Fragmentation

to be fragmented at this entity but could not be, e.g., because their “Don't

 

Fragment” flag was set.

Received Header Errors

The number of input datagrams discarded due to errors in their IP

 

headers, including bad checksums, version number mismatch, other

 

format errors, time-to-live exceeded, errors discovered in processing their

 

IP options, etc.

Unknown Protocols Received

The number of locally-addressed datagrams received successfully but

 

discarded because of an unknown or unsupported protocol.

Received Packets Delivered

The total number of input datagrams successfully delivered to IP

 

user-protocols (including ICMP).

Discarded Output Packets

The number of output IP datagrams for which no problem was

 

encountered to prevent their transmission to their destination, but which

 

were discarded (e.g., for lack of buffer space).

Fragments Created

The number of datagram fragments that have been generated as a result

 

of fragmentation at this entity.

Routing Discards

The number of routing entries which were chosen to be discarded even

 

though they are valid. One possible reason for discarding such an entry

 

could be to free-up buffer space for other routing entries.

Reassembly Successful

The number of datagrams successfully re-assembled.

 

 

Datagrams Successfully

The number of IP datagrams that have been successfully fragmented at

Fragmented

this entity.

This feature is particularly beneficial for enterprises that run demanding applications requiring substantial processing power and memory capacity. Both models support DDR4 memory, ensuring faster data access and overall system efficiency.

Storage adaptability is another key characteristic of these servers. The ES4625 and ES4649 come with multiple drive bays supporting various storage options, including SSDs and traditional HDDs. This flexibility allows organizations to configure their storage according to their specific performance and capacity needs. With support for advanced storage technologies like NVMe, enterprises can achieve unparalleled data transfer speeds, which is crucial for data-intensive applications.

In terms of manageability, both models are equipped with Microsoft’s innovative management tools. The integration of these tools facilitates easy monitoring, troubleshooting, and maintenance of server health and performance, significantly reducing downtime. Moreover, the servers are designed with enhanced security features to protect against unauthorized access and data breaches, ensuring that sensitive information remains secure.

Energy efficiency is another critical characteristic of the ES4625 and ES4649. These servers are designed with power-saving technologies that reduce energy consumption without compromising performance. This aspect is particularly advantageous for businesses looking to lower their operational costs and carbon footprint.

Overall, the Microsoft ES4625 and ES4649 offer a compelling combination of performance, flexibility, and security. They are engineered to support the increasingly complex demands of modern enterprise environments, making them a valuable investment for organizations seeking reliable, high-performing server solutions. Whether for virtualized workloads, cloud services, or heavy data computations, these servers are designed to deliver exceptional results.
