Editing Blade server (section)

== Storage ==

While computers typically use hard disks to store operating systems, applications and data, these are not necessarily required locally. Many storage connection methods (e.g. [[FireWire]], [[Serial ATA|SATA]], [[ESATA|E-SATA]], [[SCSI]], [[Serial attached SCSI|SAS]] [[Direct-attached storage|DAS]], [[Fibre Channel|FC]] and [[iSCSI]]) are readily moved outside the server, though not all are used in enterprise-level installations. Implementing these connection interfaces within the computer presents similar challenges to the networking interfaces (indeed iSCSI runs over the network interface), and similarly these can be removed from the blade and presented individually or aggregated either on the chassis or through [[Blade Server#Other blades|other blades]].

The ability to boot the blade from a [[storage area network]] (SAN) allows for an entirely disk-free blade, an example of which implementation is the [[Intel Modular Server System]].
