| Q1. |
What is the general difference between the new ProLiant ML115 G5 and the ML110 G5? |
| A1. |
The ML115 G5 utilizes AMD Opteron™ and Athlon™processors vs, Intel® Xeon®, Pentium® and Celeron® processors for ML110 G5. The ML110 G5 only offers SATA RAID 0,1 from the system board controller whereas the ML115 G5 offers SATA RAID 0,1,5 from the embedded system board controller. The ML115 G5 and ML110 G5 both have four I/O slots. However, the ML115 G5 offers x1, x8 & x16 vs. x1, x1, x8 offered by ML110 G5. |
| |
| Q2. |
Why should I buy a ML115 G5 instead of using a desktop PC as a server? |
| A2. |
There are several important differences between the ML115 G5 and a desktop PC for server deployment. First, the ProLiant ML115 G5 uses a chipset that is designed specifically for server applications. The chipset is stress tested for ECC memory support, a critical feature for server dependability. Second, the ML115 G5 was specifically designed for and rigorously tested with server applications in demanding server configurations. This testing cycle ensures optimal performance and dependability when deployed as a server. Finally, the ML115 G5 is packaged in an ergonomic chassis that makes typical server hardware configuration changes simple. By not including expensive graphics or sound cards found in desktop PCs the ML115 G5 is able to offer true server functionality at an equivalent desktop PC price. |

| A3. |
The HP ProLiant ML/DL 100 series is the entry-level of the ProLiant server line designed to deliver appropriate technology to specific market segments. The 100 series will offer a limited suite of options and leverage the various operating system enabled manageability features. The ProLiant 100 series is optimized for small / medium businesses running small business applications and enterprises running high performance technical computing solutions. |
| |
| Q4. |
How can HP offer such a competitive price point? |
| A4. |
The HP ProLiant 100 server series leverages the priorities on which ProLiant is built, reliability and performance. The focus on design provides a simplified server with the right features while limiting the cost burdened to the server and qualification process. The new 100 server series designs have tailored features that closely reflect their usage needs and the addition of qualified third-party options to enable a simpler, more affordable solution. |

| Q5. |
What is the HP Lights-Out 100 Remote Management Card? |
| A5. |
HP Lights-Out 100 Remote Management provides entry-level remote management capabilities for ProLiant ML100 Series servers. HP Lights-Out 100, when the option card is installed, allows customers or their service providers to remotely manage ProLiant 100 Series servers over a LAN or the Internet.
The ML115 G5 customers get standard IPMI 2.0 reporting embedded in the server. If the Lights-Out 100 option card is purchased, additional features such as KVM over IP and virtual media are added to the server.

| Processors and memory |
| Q1. |
How does the processor offering on ML115 G5 differ from ML110
G5? |
| A1. |
The ML115 G5 utilizes AMD Opteron™ and Athlon™ processors, whereas ML110 G5 utilizes Intel Xeon, Pentium and Celeron processors. |
| |
| Q2. |
How does the memory offering on the ML115 G5 differ from ML110
G5? |
| A2. |
The memory offering on the ML115 G5 and ML110 G5 is the same. The standard memory offering is 512 MB/1GB with a maximum of 8 GB. |
| |
| Q3. |
What is ECC memory? |
| A3. |
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 even a single-bit memory error occurs, your server stops functioning. |
| |
| Q4. |
Why do I need four memory slots? |
| A4. |
Having four memory slots 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 and growing only as fast as it is necessary. Most importantly for cost-sensitive small businesses, having four slots accommodates large memory configurations without using extremely expensive high density DIMMs. |
| |
| Options |
| Q1. |
What server specific options are available for the ProLiant ML115 G5 server? |
| A1. |
There is only one main server specific option for the ML115 G5. It is the following:
- HP Lights-Out 100 Remote Management Card
Please review the ML115 G5 QuickSpecs. |
| |
| Q2. |
How does USB booting compare to floppy? |
| A2. |
USB 2.0 offers a fast interface for
low speed peripheral devices - including storage devices. USB
drive keys support large data capacities. Available capacities
on USB disk keys can support anywhere from 16 to 300 times more
capacity than a 1.44 MB floppy disk. |
| |
| Q3. |
What is PCI-Express and why is it important? |
| A3. |
PCI Express is the latest serial transmission interface for I/O slots. With transmission rate requirements rising and interfaces moving towards serial, PCI slot is no exception.During the transition period, HP is keeping
one(1) legendary PCI 32-bit slot and offering both the PCI and PCI Express slot in the ML115 G5. By offering both the PCI and PCI Express (1x1, 1x8 and 1x16 ) slots on ML115 G5, SMB customers now have the flexibility in choosing the most suitable I/O options available today for their servers. |
| |
| Q4. |
PCI-X slot is not available with ML115 G5, what do I do with options with PCI-X interface? |
| A4. |
The one (1) embedded 32bit/33MHz 3.3V PCI slots really is capable of taking the PCI-X controllers qualified. You can rest easy using the qualified options. For a list of options, please refer to ML115 G5 QuickSpecs. |
| |
| Q5. |
Does the ML115 G5 support an Uninterrupted Power System option? |
| A5. |
Yes, a UPS option has been tested and is available for the ML115 G5. Currently, HP supports the usage of an HP T750 or T1000 UPS for the ML115 G5. |
| |
| Storage |
| Q1. |
What is RAID? Why do I need it? |
| A1. |
RAID stands for Redundant Array Of Independent Disks and is a way of storing data across several different hard disks. By placing data on multiple disks, read/write operations can overlap and improve performance. Many RAID configurations also provide data redundancy, which increases the fault tolerance of the system. RAID appears to the operating system to be a single logical hard disk. RAID employs the technique of striping, which involves partitioning each drive's storage space into units ranging from a sector (512 bytes) up to several megabytes. The stripes of all the disks are interleaved and addressed in order. RAID is typically used for increased data integrity and better performance. Optional RAID cards for both SATA as well as SAS are available on the ML115 G5. |
| |
| Q2. |
Why should I buy a RAID array controller? |
| A2. |
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 three 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 re-builds the array and once again ensures 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% or more improvement
over the straight drive controllers. |

| Q3. |
What other storage options are available for the ML115 G5? |
| A3. |
Additional storage options for the ML115 G5 are:
- A DVD- RW option, which is available for simple storage back up
- Two front, two inside, and two rear USB 2.0 ports, which are available to replace to USB drive keys, external USB floppy, external disk to disk solutions, and HP USB tape drives.

| |
| Q4. |
Does the ML115 G5 support hot-plug hard disk drives? |
| A4. |
No, the ML115 G5 does not support hot-plug hard disk drives. Utilizing a non hot plug solution helps HP to offer the highest value solution to SMB customers.
If a Hot Plug hard disk drive is desired, please consider the ProLiant ML310
G5 for your solution. |
