IBM offers: The form factor Tower: IBM System x3400, IBM System x3500. In the form factor Rack Mount: IBM System x3455, IBM System x3550, IBM System x3650, IBM System x3655. The company offers DELL: The form factor Tower: DELL PowerEdge 1900, Dell PowerEdge 2900. In form factor Rack Mount: Dell PowerEdge 1950, DELL PowerEdge 2950, DELL PowerEdge 2970. In the form factor Tower servers from HP have demonstrated maximum extensibility, while not losing much IBM's price.
Dell is clearly losing its competitors. Consider a server in the performance of Rack Mount. The situation with the servers performed RackMount does not change. All also very affordable, IBM, HP a little more expensive, but the wealth of choice much more. Dell and are lagging behind competitors.
In conclusion, we note the server HP DL320. It fairly inexpensive and practical file server, which has no analogues among the other manufacturers. Through the use of dual-core Intel Xeon, memory DDR2 (up to 8GB) and the total capacity to 10.5 terabytes, the server perfectly suited for data – the centers of large companies and small organizations. Part 3. Enterprise Servers The final part of this review, we consider the most popular models of enterprise-class servers: HP offers: The form factor Tower: HP ProLiant ML570 G4 form factor Rack Mount: HP ProLiant DL580 G4, HP ProLiant DL585 G2 IBM offers: The form factor Tower: IBM System x3800 in the form factor Rack Mount: IBM System x3755, IBM System x3850 offers DELL Company: The form factor Tower: DELL PowerEdge 6800 in the form factor Rack Mount: Dell PowerEdge 6850, DELL PowerEdge 6950 is not strange, but the servers from IBM's identical servers from HP, but cheaper by 10%. The decision by Dell is not much inferior to peers, as significant difference between SAS and SCSI, though there certainly is more common SAS. Consider a server in the performance of Rack Mount. In segment of the enterprise server can not identify a clear winner, because considered producers offered nearly identical to the server, the difference between them is almost essential. But still wanted to put on a space solutions from HP and IBM, as the second Dell, because solutions from Dell inferior to the interface of hard drives and in the amount of RAM, but stand at this price.
