RH2288E V2 hard disk

3

HDDs are hot-swappable and store data for the RH2288E V2.

The RH1288A V2 supports eight 2.5-inch SAS/SATA HDDs or SSDs.

Total storage capacity (8 x 2.5-inch hard disks):
? SAS HDDs: 9.6 TB
? SATA HDDs: 8 TB
? SSDs: 4.8 TB
Note:
The maximum storage capacity of the server varies depending on the maximum capacity of a single hard disk.

The server supports RAID 0, 1, 10, 1E, 5, 50, 6, and 60, provides an iBBU or supercapacitor to protect cache data from power failures, and supports RAID state migration, RAID configuration memory, self-diagnosis, and web-based configuration.

The mainboard can be configured with a SAS card or SAS RAID controller card (with a maximum of 1 GB cache) to improve hard disk storage performance and ensure user data security.

The RAID controller card does not occupy a standard PCIe slot, which improves system scalability.

The RH2288E V2 provides two ports for connecting to an embedded USB flash drive and an embedded USB flash memory card.

The four NICs of the RH2288 V2 are GE NICs on the mainboard while the NICs of the RH2288H V2 are flexible NICs. The number of PCIe slots on riser cards is also different. The RH2288E V2 supports holding guide rails for installation. For details, see their respective user guide.

Whether the USG6650 hard disk has a hard disk card
The USG6650 supports two types of hard disks, namely, SM-HDD-SAS300G-A and SM-HDD-SAS300G-B. Model A uses the tray of the device, and model B has its own tray.

Query hard disk SN of a server
The hard disk serial number (SN) starts from 2102. You can obtain SN information from the SN label on the hard disk case.

Hard disk capacity expansion for the USG6000 series
The USG6650/6660/6670/6680 supports dual hard disks. Do as follows to install a hard disk on the USG, which has been running for some time with a single hard disk: 1. Ensure that all configurations are saved. 2. Run the disk offline command in the system view. Wait for about 30 seconds until the system indicates that the hard disk stops working, remove the filler panel from the hard disk slot, and install a new hard disk unit. a. Remove the filler panel from the hard disk slot. HDD1 is used as an example. b. Hold the handlers of the tray and push the tray along the guide rails inside the hard disk slot till the tray panel aligns with the panel of the device. c. Press the tray handler inwardly to restore the tray. d. In the system view, run the reset raid primary-disk disk-id command to create a RAID group using disk-id as the primary disk for data synchronization. In this example, the command shall be reset raid primary-disk 0. Several hours later, run the display disk information command. If Filesystem Status is Mounted and DiskRaidMode is ACTIVE, both hard disks work properly. Note: After the RAID is created, the data in the active disk will be synchronized to the backup disk and the original data on the backup disk will be overwritten. Select the disk-id of the active disk before creating RAID.
