6 Dell EMC SC Series with Red Hat Enterprise Linux 7x | CML1071
1 Overview
SC Series storage provides Linux-compatible and SCSI-3 compliant disk volumes that remove the complexity
of allocating, administering, using, and protecting mission-critical data. A properly configured SC Series array
removes the need for cumbersome physical disk configuration exercises and management along with
complex RAID configuration practices. The SC Series array also provides RAID 10 speed and reliability at the
storage layer so that volumes do not need to be further RAID-managed within the Linux operating system
layer.
The full range of Linux utilities such as mirroring, backup, multiple file systems, multipath, boot from SAN, and
disaster recovery can be used with SC Series volumes.
1.1 New in RHEL 7.x
RHEL 7.x delivers dramatic improvements in reliability, performance, and scalability. This paper identifies
improved RHEL 7.x features that provide simpler use and integration with the SC Series storage and features.
 XFS is the new default filesystem for boot, root, and user data partitions.
 The XFS filesystem size limit has increased from 100TB to 500TB, and the ext4 filesystem size limit
has increased from 16TB to 50TB.
 New software implementation of the iSCSI and Fibre Channel over Ethernet (FCoE) targets are
located in the kernel, instead of the user space.
