1 Product Comparison 1.1 Overview Evolution of Dell™ PowerVault™ DAS portfolio with the introduction of 6Gb/s SAS (SAS 2.0) in our JBOD arrays. These arrays will connect to Dell™ PowerEdge™ 11G servers using the Dell™ PowerEdge™ RAID (PERC) H800 Host-RAID Adapter. The MD1200 is follow-on to the MD1000, and the MD1220 is follow-on to the MD1120. Table 1 shows a comparison between these versions. Table 1.

4 Product Support 4.1 Host-RAID Adapter Support The PowerVault™ MD1200 and MD1220 require the PERC H800 for Server connectivity. The PERC H800 is a PCIe 2.0, dual port (2 x4), hardware RAID controller offering 512MB standard battery-backed cache and RAID level support for RAID 0, 1, 5, 6, 10, 50, and 60. The key features of the PERC H800: 6Gb/s SAS (SAS 2.0) Enables daisy-chaining up to 8 enclosures (4 per port) Enables mixing 2.5-inch and 3.
4.5 Drive Support Dell™ PowerVault™ MD1200 and MD1220 enclosures support SAS hot-pluggable HDDs (hard-disk drives) and SSDs** (solid-state drives). MD1200 allows for both 3.5-inch and 2.5-inch** form factor drives, and MD1220 allows for 2.5-inch form factor drives. Refer to Table 4 for Drive Support details. Table 4.

5.5 Enclosure Management Module Each EMM provides the following data path and enclosure management functions for the enclosure: • Monitoring and controlling enclosure environment elements such as temperature, fan, power supplies, and enclosure LEDs. • Controlling access to hard drives. • Communicating enclosure attributes and states to the host server. Figure 7. Enclosure Management Module Table 9.
Item EMM INDICATOR AND FETAURE DESCRIPTION Indicator, Button, or Icon Description Connector update is in progress. Blinks amber (On 250 ms Off 250 ms [two times]; Off 1000 ms) when the enclosure is unable to communicate with enclosure devices. Blinks amber (On 250 ms *Off 250 ms [four times]; Off 1000 ms) when a firmware update fails. Blinks amber (On 250 ms Off 250 ms [five times]; Off 1000 ms) when the firmware versions are different between two EMMs in an enclosure. *indicates that the LED blinks fast.
5.6 Power Indicator Codes Figure 8. Table 10. Item 1 2 3 Power Indicator Codes Power Indicator Description POWER INDICATOR AND FETAURE DESCRIPTION Indicator, Button, or Icon Description Connector DC Power The LED lights green when the DC output voltage is within the limit. If this LED is off, it indicates that the DC output voltages are not within the limit. Power supply/cooling fan The LED lights amber when the DC output voltage is not within fault the limit or a fault with the fan is detected.
• In a split-mode configuration the enclosure is connected to either two host controllers or two ports on a single host controller. The enclosure can be connected to two different host servers in a split mode configuration. Each server sees the enclosure as an independent device with half of the total enclosure slot capacity. Table 10 lists the drives that are controlled by each enclosure management module (EMM) in a split-mode configuration.
