The system should have already changed the value to reflect the newly installed memory.

13If the value is incorrect, one or more of the memory modules may not be installed properly. Repeat step 2 through step 12 of this procedure, to ensure that the memory modules are firmly seated in their sockets.

14Run the system memory test in the system diagnostics. See "Running the Embedded System Diagnostics" on page 140.

Expansion Cards and Expansion-Card Risers

Your system supports up to four PCI Express (PCIe) expansion cards installed in connectors on an expansion-card riser.

Your system has an expansion-card riser 1 that provides three x4 Gen2 PCIe expansion-card slots and one x8 Gen2 PCIe expansion-card slot.

CAUTION: Expansion cards can only be installed in the slots on the expansion-card riser. Do not attempt to install expansion cards directly into the riser connector on the system board.

Expansion Card Installation Guidelines

The expansion-card slots support full-height, half-length cards.

The expansion-card slots are hot-swappable.

PCI Express Generation 2 expansion cards are supported in all the slots.

All the slots are x8 connectors.

CAUTION: To ensure proper cooling, only one of the two expansion cards can have a power consumption of greater than 15 W (up to 25 W maximum), not including the integrated storage controller.

Table 3-2 provides a guide for installing expansion cards to ensure proper cooling and mechanical fit. The expansion cards with the highest priority should be installed first using the slot priority indicated. All other expansion cards should be installed in card priority and slot priority order.

This feature dramatically reduces the amount of disk space required, allowing organizations to optimize their storage solutions and decrease associated costs. The DR4000 can provide deduplication ratios of up to 30:1, depending on the data being backed up.

The DR4000 is built on a robust architecture that combines high-performance hardware with the latest software technologies. Its dual-controller design ensures high availability and redundancy, making it a reliable solution for critical data protection tasks. The appliance is equipped with powerful processors and ample memory, enabling efficient handling of multiple backup operations simultaneously without compromising performance.

In addition to its deduplication capabilities, the DR4000 supports a wide range of backup protocols, including NFS, CIFS, and iSCSI, making it compatible with various backup applications. This flexibility allows organizations to easily integrate the appliance into their existing IT infrastructure, regardless of the backup software they are currently using.

Another notable characteristic of the DR4000 is its scalability. As businesses grow and their data requirements increase, the DR4000 can be easily expanded to meet new demands. Organizations can add more capacity by installing additional storage drives or even leveraging cloud storage options for offsite backups. This adaptability makes the DR4000 an ideal solution for businesses looking to future-proof their data protection strategies.

Furthermore, the Dell DR4000 features comprehensive management tools that streamline backup operations and enhance monitoring capabilities. The user-friendly interface provides real-time insights into backup performance, utilization, and overall health of the system, allowing IT administrators to make informed decisions regarding their data protection strategies.

In summary, the Dell DR4000 is an exceptional choice for organizations seeking an efficient, scalable, and reliable backup solution. Its advanced deduplication technology, robust architecture, multi-protocol support, scalability, and comprehensive management features make it a strong contender in the data protection market. By choosing the DR4000, businesses can ensure their data is well-protected and easily recoverable, enabling them to focus on their core operations without the worry of data loss.
