KERNSAFE - iSCSI SAN Software and Storage Virtualization

RAM disk is a iSCSI device created from memory space in server host. KernSafe iSCSI SAN can create a disk in the memory of server host machine, because RAM disk is in physical memory, it provides fastest accessing speed to all the initiators. RAM disk is used for user to share most frequently used data files. It is suitable for working in a performance critical environment, such as disk less boot. Warning : All the changes will be lost after server reboots, turning off the computer will result in deleting Ram disk device.
