3.3 Metadata targets
The ME4024 array is fully populated with 24 x 960 GB SAS SSDs. An optimal way to configure the 24 drives
for metadata is to configure twelve MDTs. Each MDT is a RAID 1 disk group of two drives each. Figure 4
shows how the MDTs are configured.
Configuration of metadata Targets in the ME4024 storage array
The metadata target is formatted with ext4 file system because ext4 performs well with small files and small
file operations. Additionally, BeeGFS stores information as extended attributes and directly in the inodes of
the filesystem. Both of these work well with ext4 file system.
