Processors and memory

Q1.What are dual-core processors?
A1.

Dual core processors are just that, processors with two computing cores on them. This theoretically gives a giant increase in computing power per processor in multithreaded applications. In the ML150 G3, dual core processors give customers the chance to have up to four computing cores in the server.


Q2.What is processor cache and why is it useful?
A2.

Cache memory on the processor chip is faster than main memory. It allows frequently accessed data to be available to the processors with less waiting. Both larger available caches and more levels of cache improve performance by reducing the time to fetch the data. In addition, larger processor cache reduces the average number of cache misses, further enhancing performance.


Q3.What is a Front Side Bus (FSB)?
A3.

The Front Side Bus (FSB) is the pipeline that carries information to and from the CPU to the memory and chipset. The wider (or faster) the pipeline, the more transactions per second are carried, the better the system performance.


Q4.What is ECC memory?
A4.

ECC memory, or Error Checking and Correcting memory, helps protect a 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 even a single-bit memory error occurs, the server stops functioning.


Q5.Why do I need four memory slots?
A5.

Having four memory slots most likely enables systems to accommodate more total memory than a two or three slot solution. Additionally, having up to 3 open slots allows users to add memory incrementally, growing only as fast as is necessary. Most importantly for cost-sensitive small businesses, having four slots accommodates large memory configurations without using extremely expensive high density DIMMs. For example, loading 2GB in two slots costs $3,000-$4,000 more than loading 2GB in four slots (2x1GB DIMMs vs. 4x512MB DIMMs).


Connectivity

Q1.What is Gigabit and why is it important to me?
A1.

Gigabit Ethernet is a networking standard for high performance networking. Today's gigabit technologies are capable of transferring data at rates exceeding 800 Mbps, about eight times the rate of 100Base-T Ethernet. In the future, it is expected that improvements in both hardware and software will lead to gigabit Ethernet achieving speeds of up to 1000Mbps (hence the name, gigabit).

Implementing gigabit Ethernet over existing Cat-5 networks will lead to improved network performance as it increases the bandwidth available for information to pass along the network.


Q2.What is the USB support on the ML150 G3?
A2.

The ML150 G3 supports USB 2.0. Seven USB ports are provided in the server. Two ports are on the front, three are on the rear, and two are internal.


Q3.Why is PCI-X important?
A3.

PCI-X support is critical for overall server performance. In the ML150 G3, the PCI bus hosts all networking devices and PCI cards such as gigabit NICs or SCSI disk controllers. Moving from a 32-bit (as is still used in desktops) to the PCI-X bus quadruples the amount of data that can be transferred for a given unit of time. To achieve true gigabit NIC support (send & receive), at least a 64-bit PCI bus is required. When running multiple tasks in parallel, such as communicating with the network and writing to the SCSI drives, the higher bandwidth PCI-X bus reduces bottlenecking that can impact system performance.


Q4.What is PCI-Express and does this server support PCI-Express adapters?
A4.

PCI-Express is a new interface for add-in card applications that require bandwidths in excess of 1 GByte/s. PCI-Express cards look very similar to conventional PCI and PCI-X cards and are installed in the server the same way. However, the PCI-Express interface is different from the PCI and PCI-X interface, so slots must be designed for one or the other. As more and more applications require higher bandwidths, it can be expected that more and more PCI-Express slots appear in servers. PCI/PCI-X slots will remain, however, for backwards compatibility. The ProLiant ML150 G3 supports PCI-Express mode with two slots. One slot is a x8 slot and the other is a x4 slot (in a x8 connector).


Options

Q1.What options are available for my ProLiant ML150 G3 server?
A1.

Options include but are not limited to:

  • 2nd Processor
  • Single and double DIMM Memory Kits
  • SAS/SATA HBA
  • Universal SAS and SATA hard disk drives
  • PCI-X and PCI-Express Gigabit NICs
  • Uninterruptible Power Supplies

For a complete list of supported options, please see the product QuickSpecs.


Q2.How do I decide between SATA hard drives and SAS hard drives?
A2.

It depends on the application environment - if cost is more important than performance or security and the types of applications that do not place a great deal of stress on the hard drives are being run on the server, then SATA drives may be good enough. However, if drive reliability or performance is more important; or if the application environment will put a great deal of stress on the drives, then SAS hard drives are recommended over SATA HDD.


Q3.Why should I utilize RAID?
A3.

There are many benefits to using a RAID 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, data can mirrored (RAID 1) across two hard drives or to sprayed 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, data can be sprayed 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.

The ML150 G3 server ships standard in many models with an embedded motherboard RAID controller. This embedded functionality is more stable and secure than OS based RAID, yet not as fast or powerful as a HW RAID solution. HP offers customers the choice of RAID solutions to best fit their deployment needs.


Q4.What back-up technology is supported on the ML150 G3?
A4.

The ML150 G3 offers support for the following HP StorageWorks DAT Drives:

  • DAT 24 USB Tape Drive
  • DAT 40 USB Tape Drive
  • DAT 72 USB Tape Drive
  • Ultrium 232 Tape Drive (requires purchase of a SCSI adapter)

Q5.Can I deploy the ML150 G3 in a rack?
A5.

Yes, the ML150 G3 has a rack rail and bezel kit available for order with the server (408697-B21). This is different than the previous ML150 G2 which was only rackable via a shelf.


Server Management

Q1.What is the HP ProLiant ML150 G3 Lights-Out 100 Remote Management Card?
A1.

The new optional HP ProLiant ML150 G3 Lights-Out 100 Remote Management Card provides entry level remote management functionality and basic system board management capabilities.

Standard in-band management provided with every ML150 G3 server includes hardware health monitoring via standard IPMI management applications (fan, temperature, power supplies, VRM - status, presence and redundancy).

The addition of the Lights Out 100 card provides the following:

  • Remote KVM
  • Virtual floppy, CD
  • Virtual power
  • System event log access
  • OS independent health status
  • Secure command line access (SSH)
  • Secure browser access (SSL)

  • SMASH CLP
  • IPMI 2.0 via OS based management apps
  • Telnet access

HP Lights Out 100 in the ML150 G3 provides an unprecedented amount of remote management capabilities in the entry level server segment.


Q2.What is HP Systems Insight Manager and will it support the 100 Series?
A2.

HP Systems Insight Manager (HP SIM) is the foundation for HP's unified infrastructure management strategy. It provides hardware level management for HP ProLiant, Integrity, and HP 9000 servers; HP BladeSystems; and HP StorageWorks MSA, EVA, and XP storage arrays. HP SIM also provides management of non-HP gear through industry standards like SNMP, WMI, WBEM, SSH, etc.
