Please refer to the portfolio positioning general Q&A list for more information.
|
|
| Q4. |
What chipset is HP using in the ProLiant DL145 G3 and what are its advantages? |
| A4. |
The ProLiant DL145 G3 uses the ServerWorks HT2100 and HT1000. This chipset implementation supports up to two Opteron processors, 32GB of PC2-5300 DR2 memory, x16 PCI-Express, PCI-X 133MHz and HTX functionality. |
|
 |
| Processor & Memory |
| Q1. |
Does the DL145 G3 support interleaved memory? |
| A1. |
Yes. Memory in the DL145 G3 is 2-way interleaved for even better performance. As a result, memory DIMMS must be populated in identical pairs (interleaved).
|
|
| Q2. |
What memory does the new ProLiant DL145 G3 use and what are its benefits? |
| A2. |
The HP ProLiant DL145 G3 server uses PC2-5300 Double Data Rate II (DDR2) SDRAM running at 667MHz with Advanced ECC functionality. DDR2 SDRAM is a next-generation SDRAM technology. SDRAM data is transferred on the rising edge of every clock cycle with each DIMM. The memory chip on DDR DIMMs performs transactions on both the rising and falling edges of the clock cycle, effectively doubling memory bus clock rate yields.
|
|
| Q3. |
How do customers expand the memory on the ProLiant DL145 G3? |
| A3. |
The ProLiant DL145 G3 offers models that ship standard with either 1GB of PC2-5300 ECC SDRAM memory (2×512MB), 2GB of PC2-5300 ECC SDRAM memory (2×1GB) or 4GB of PC2-5300 ECC SDRAM memory (2×2GB). The architecture of the ProLiant DL145 is such that each processor supports up to 4 DDR2 SDRAM DIMMs. Memory must be added in pairs, with the ideal configuration being one with identical memory configuration for each CPU board, up to 32GB (8×4GB). The option kits are as follows:
| Memory option kit |

| Options |
| Q1. |
How does USB compare to floppy? |
| A1. |
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. |
|
| Q2. |
Can the front USB port on the DL145 G3 be used as a floppy replacement? |
| A2. |
Utilities are now available to allow the use of USB instead of floppy for a number of tasks, including system boot from USB drive key.
|
|
| Q3. |
How does the PCI-X and HTX options work? |
| A3. |
The DL145 G3 has support for an optional PCI-X card that replaces the low-profile PCI-Express slot in the system and HTX riser card that replaces the full-length PCI-X slot in the system. The optional PCI-X Riser card is p/n 411625-B21 and the optional HTX riser card is p/n 411627-B21. |
|
| Q4. |
Can I upgrade my HP ProLiant DL145 G3 non-hot plug model to support hot plug drives? |
| A4. |
Yes. There is an optional hot plug backplane kit (p/n 411623-B21) that can be installed to allow support of hot plug hard drives. This is required for support of all SAS drives. |
|
| Q5. |
Can I deploy Serial Attached SCSI (SAS) hard drives in the DL145 G3? Does the DL145 G3 support Serial Attached SCSI (SAS) RAID? |
| A5. |
Yes. The DL145 G3 supports hot plug SAS hard drives standard in DL145 G3 SAS BTO models or as an option to the DL145 G3 SATA models. If deploying SAS as an option, customers will need to purchase the optional hot plug backplane option kit p/n 411623-B21.
Yes. The HP Smart Array E200 RAID Controller (p/n 409180-B21) allows you to configure SAS or SATA drives in either RAID 0 or 1 volumes in the hot plug models. |

| Q2. |
What are the advantages of AMD's new PowerNow! technology, and what operating systems and processors support the new technology? |
| A2. |
AMD's PowerNow! is an ACPI-based OS demand-based switching technology that allows the processors to run dynamically at different frequencies and voltages depending upon CPU computing demand. Therefore, PowerNow! enables lower server power consumption without compromises in performance.
AMD PowerNow! Technology enables the CPU to:
- Run at multiple performance states (frequency and voltage combinations)
- Switch among multiple performance states (controlled by software), without having to reset CPU or change FSB frequency
Certain operating systems feature support for PowerNow!, which is offered on the following Opteron-based servers:
| ProLiant server |
AMD PowerNow!
supported |
| DL145 G2/G3 |
 |
| DL385 |
|
| DL5851 |
|
| BL25p |
|
| BL35p |
|
| BL45p |
|
| 1 |
ProLiant DL585 servers with 1.8GHz or lower single-core processors, or 2.2GHz (Rev. C) single-core Opteron processors do not support PowerNow! |
Minimum operating system versions for AMD PowerNow!:
| Operating system |
AMD Opteron
supported |
| Windows 2003 SP12, 3 |
|
| SLES 9 SP2 (64-bit)4 |
|
Operating systems that do not offer support for PowerNow! include:
- Windows 2000, Windows 2003 (base media)
- RedHat EL 3
- NetWare
- UnixWare/OpenServer/Solaris

| Performance |
| Q1. |
What types of applications see the most performance benefit from Opteron technology? |
| A1. |
Applications that require high bandwidth and low latency access to system memory benefit from Opteron technology, especially true for high performance cluster computing but also applicable to a large number of commercial applications as well.
HP expects 2-way and 4-way platforms based upon Opteron technology will provide more system memory bandwidth at lower latencies than current x86 based platforms. Also, Opteron technology allows memory and I/O resources to scale with additional processing power providing increased levels of system resources as computing needs increase. Combining resource scaling with Opteron's HyperTransport technology allows for those system resources to be shared effectively across all processing units benefiting many multi-threaded applications and provides for high levels of scalability from UP to DP to 4-way processing.
Additionally, customers who need to run existing 32-bit applications along with 64-bit applications can benefit from the simultaneous 32-bit and 64-bit computing capabilities of Opteron technology. In those environments, 32-bit application performance is not compromised. Also, applications that need large memory addressing such as those with large datasets (financial and scientific modeling applications) or must manage a large number of concurrent users or application threads such as large databases and data warehouse applications for solutions in customer relationship management (CRM), supply chain management (SCM), enterprise resource planning (ERP), and digital rights management (DRM) systems can benefit from Opteron's ability to access up to 256 Terabytes of memory address space.

| Q2. |
What is the performance of these new servers? |
| A2. |
Opteron specific benchmarks can be found on AMD's website. ProLiant specific benchmarks will be posted to our website once they are completed. |
