Answers

General
Q1. Where can I find detailed information on the ML310 G4 specifications and supported options?
A1. The ML310 G4 QuickSpecs include descriptions of all models of the ProLiant ML310 G4, an extensive list of supported options from HP, and technical information about the server.
Q2. Are there any features of the ML310 G3 that are not included on the ML310 G4?
A2. Yes. The ML310 G3 supports Ultra320 SCSI hard drives, the ML310 G4 does not. The ML310 G4 transitions from U320 to Serial-Attached SCSI (SAS).

For more information on standard features and options see the ML310 G4 QuickSpecs.
Q3. Does HP offer a racking solution for my ProLiant ML310?
A3. Yes, the ProLiant ML310 G3 and G4 can all be deployed in a rack, using the ProLiant ML310/ML330 Tower-to-Rack Enabling Kit (P/N 417705-B21). This kit includes a shelf with two thumbscrews that connect to the back of the server to enable service in the rack. In addition, the kit also includes a cable management solution and universal rails for easy installation in Compaq, HP, or many third-party racks.
Processors and memory
Q1. How do the processors on the ML310 G4 differ from the processors on the ML310 G3?
A1. The ML310 G4 offers support for three Intel®  processors: Dual-core Intel®  Xeon®  (3000 Sequence), Pentium®  D (800 or 900 Series),and Intel®  Celeron®  (300 Series). Dual-core processors have two execution cores, making it possible to execute two application instructions at one time.
Q2. What is ECC memory?
A2. ECC memory, or Error Checking and Correcting memory, helps protect your server from failure due to errors in the transfer of data to and from the memory. Unlike standard memory, ECC memory can actually detect and correct single-bit errors. With standard memory if a single-bit memory error occurs, your server stops functioning.
Q3. Why should I buy a RAID array controller?
A3. There are many benefits to using a RAID array controller in a server, but the primary benefits fall into two main categories: improved data integrity and higher performance.

Data Integrity: Using a RAID controller, you can choose to mirror data (RAID 1) across two hard drives or to spray that data across 3 or more hard drives (RAID 5). In both cases, if a hard drive fails, then the data will not be lost. Once the failed hard drive is replaced, then the RAID controller can re-build the array and once again ensure the integrity of that data.

Performance: Using a RAID controller, you can choose to spray data across three or more drives either in a non-secure manner (RAID 0), meaning that if a drive fails then data will be lost, or in a secure manner (RAID 5), meaning that if a drive fails then no data will be lost. Both RAID 0 and RAID 5 lead to improved performance of the hard-drive subsystem over standard straight drive controllers (without RAID). This performance benefit can be as much as 30% improvement or more over straight drive controllers.

Remote management
Q1. What is Integrated Lights-Out 2?
A1. Integrated Lights-Out 2 (iLO 2) is HP's fourth generation of Lights-Out management technology now delivering the industry's most complete, high-performance, out-of-band remote management solution. iLO 2 is a new management processor and firmware that will enable a new generation of innovative and standards based remote management capabilities for HP ProLiant servers. The introductory firmware release for iLO 2 enables new remote consoles with KVM over IP performance and improved ease of use. For more information, visit the iLO 2 web site
Q2. How can Integrated Lights-Out 2 benefit my business?
A2. Integrated Lights-Out 2 allows you or your server support staff to have full remote control of a ProLiant server for routine administration or occasional maintenance. With iLO 2, you can perform virtually any task remotely as if you were at the server using its keyboard, mouse and monitor, power button and floppy, CD or USB key. You are in control whether the remote system is powered off, distressed or running normally. iLO 2 is the single, remote control solution that dramatically reduces the need to travel to a server or to find qualified local support when responding to a problem or administering ProLiant servers. iLO 2 offers industry leading HP Lights-Out remote management and control that has resulted in reduced operational costs and increased availability on millions of ProLiant servers.
