Notes on Installing SSD
 Do not mix SSD and SAS disk drives in the same RAID group
 LUN concatenation with SAS Volume is unavailable
 Eco-mode cannot be used with SSD
 Hot Spare must also be a SSD when a RAID Group is
configured with SSD

Multipath Functionality (1)
 All ETERNUS DX Entry and DX Midrange systems support
assigned access path configuration
 Active-Active / Preferred Path
 Active/Active
 Each RAID Group has an assigned CM (RAID Group owner)
that handles I/O to this RAID Group and its associated
Volumes
 If I/O is sent to the CM that is not the RAID Group owner, this
I/O is transferred internally over the CM midplane to the owner
CM
 This has a slight impact on the I/O performance
 RAID Groups are assigned to a CM with the ETERNUS
Manager GUI
 Either manually or automatically when a RAID Group is created
 It is possible to change the assigned CM later if needed

Multipath Functionality (2)
 This is a typical I/O Multipath configuration
 LUN1 is mapped to the server via two
ETERNUS DX ports, one on CM0 and
one on CM1
Data
LUN-1
MP-Driver
 Now the Multipath driver can pass
the data via both physical lines to
a particular Volume in the DX system
 In this assigned CM configuration
the LUN1 is controlled by CM0
CM0
CM1
 The Multipath driver controls how the
access paths are utilized
• For example, these MP drivers send data
directly to the assigned CM path as long
as the CM is fully functional
• ETERNUS Multipath Driver (EMpD)
• VMware vSphere® Multi Path Driver

Controller Module Failover
 In case a controller fails, the RAID Group ownership is handed
over to the other controller and the operation can continue
 In this example the CM1 now controls the RAID Groups owned
previously by the CM0

Cache Mechanism
 Cache memory on each CM is divided into two logical areas
 Local area and Mirror area of the other CM
 ETERNUS DX Entry and Midrange models
 Entry models with single or dual CM, Midrange always with two CMs
 For reliability data is mirrored in cache memory between the two CMs
 Cache data is backed up in case of a main power failure
 DX80 S2 and DX90 S2
• Onto nonvolatile memory (NAND Flash) on CM
• System Capacitor Unit (SCU) on the CM provides
power during the fast copy process
 DX410 S2 and DX440 S2
• Onto nonvolatile memory (SSD) on CM
• Battery Backup Units (BBU) supply power during the
copy process

Cache Data Backup to Non-volatile Memory
 Protects cache data in case of a long time power failure
 There is no limit on the retention time of the data backed up to a
nonvolatile memory
• Entry models use NAND Flash, Midrange models use SSD
Memory backup using batteries

BUD - Boot-up and Utility Device
 New feature in each CM of the DX S2 systems
 DX80 S2 and DX90 S2
 BUD is a USB memory device holding the configuration data
 Cache data in case of power failure stored in a Flash memory
 DX410 S2 and DX420 S2
 BUD is an SSD holding the configuration data
 BUD is also used to store the cache data in case of power failure
