Introduction

 

This hardware manual briefly introduces the DVA 12 T iSCSI-to-SATA-II storage subsystem

 

shown in Figure 2.1.

2.1

Product Overview

 

The RAID subsystem comes with two (2) Ethernet host ports capable of large I/O transfers

 

over iSCSI packets. The subsystems come in a 2U-profile rack-mountable chassis which

 

houses a RAID controller module featuring complete RAID configuration and maintenance

functionality. The subsystem’s operation is protected by redundant hot-swappable power sup- plies and cooling fan modules. Designed for high level of availability, all major components are hot-replaceable including its Li-ION battery, and the RAID-protected disk drives.

The iSCSI storage supports the connection to network initiators compatible with the IETF iSCSI standard (RFC 3720).

The subsystem facilitates data packaging, using the Internet SCSI (iSCSI) protocols, and transmission of block I/Os over LANs. The subsystem is ideal for location-independent data storage, backup, and retrieval. It combines the capabilities and block-level performance of RAID storage with the high-speed, low-cost, and long-distance Ethernet networking technolo- gies.

Configured arrays are easily combined with multiple ID/LUNs on host ports, turning massive capacity into manageable units for data-sharing in a heterogeneous environment.

Fig. 2.1 RAID Subsystem DVA-12T

This high-density subsystem supports up to twelve (12) hot swappable, SATA-II hard drives in a 2U-profile chassis. The subsystem is powered by the RAID controller board featuring the lat- est ASIC266 ASIC as the XOR engine and a pre-installed 1 GB DDR RAM DIMM module.

The controller board is housed in a metal canister and is referred to as the “controller mod- ule.” The controller module is comprised of a PCB board, a rear faceplate, and a metal canis- ter. The controller module is accessed through the rear of the subsystem with the help of two hand screws. An battery backup unit (BBU) can be installed in the upper left side of the con- troller module (when viewed from the rear of the subsystem). The BBU is hot swappable and is accessed through the rear of the subsystem enclosure.

Two (2) RJ-45 connectors connect the RAID controller to network switches or Ethernet ports of independent devices. Three (3) hot-swappable cooling modules protect the subsystem from overheating, and two (2) hot-swappable power supply unit (PSU) modules provide con- stant power to the subsystem. The modular nature of the subsystem and the easy accessibility to all major components ensure the ease of the subsystem maintenance.

A maximum of 31 units can be connected to the subsystem.

iSCSI Host Ports

Connectivity: - The iSCSI host ports are capable of 2 GBps Ethernet with full duplex transmis- sion. Storage volumes are associated with simulated ID/LUNs on the host channels. These vol- umes then appear as iSCSI targets over the network. The connection of these host ports is

DVA-12T specifications

The Bosch Appliances DVA-12T is a standout in the field of kitchen ventilation, offering a seamless blend of high performance, modern design, and innovative technology. This under-cabinet range hood is engineered to deliver top-notch airflow while maintaining a surprisingly quiet operation, making it an ideal choice for both professional and home chefs.

One of the primary features of the DVA-12T is its powerful ventilation system, which boasts an impressive airflow capacity of 400 CFM. This ensures that even the most intense cooking sessions are met with adequate ventilation, effectively removing smoke, odors, and grease from the kitchen environment. The appliance is equipped with a three-speed fan that allows users to choose the appropriate level of airflow based on cooking needs, from simmering to high-heat sautéing.

In terms of design, the Bosch DVA-12T exemplifies contemporary aesthetics with its sleek stainless steel finish, which not only enhances the kitchen's appearance but is also easy to clean. Its low-profile design allows it to fit neatly under cabinets, making it a space-saving solution that does not compromise on power or effectiveness.

The DVA-12T is fitted with an advanced lighting system that includes LED lights, providing bright and efficient illumination over the cooking area. These lights enhance visibility while cooking and contribute to energy savings compared to traditional incandescent lights.

Moreover, the DVA-12T features a dishwasher-safe baffle filter that efficiently captures grease and enhances the longevity of the appliance. This user-friendly feature simplifies maintenance, allowing consumers to keep their range hood functioning optimally without hassle.

One notable characteristic of the Bosch DVA-12T is its quiet operation. With noise levels that remain as low as 46 decibels, this range hood ensures that you can enjoy conversations and the ambiance of your kitchen while cooking. This is achieved through advanced engineering that minimizes turbulence and promotes smooth airflow.

In conclusion, the Bosch Appliances DVA-12T stands out for its powerful ventilation, stylish design, user-friendly features, and quiet operation. It's an ideal choice for anyone looking to enhance their culinary environment while maintaining a serene atmosphere in the kitchen. Whether for everyday cooking or gourmet meals, this range hood represents the essence of Bosch's commitment to quality and innovation.
