The most - common example is TCP over IP, which allows to pass through firewalls and - create remote backup storage in a different datacenter. DST requires - single port to be enabled on the exporting node and outgoing connections - on the local node. - - DST works with in-kernel client and server, which improves performance by - eliminating unneded data copies and by not depending on the version - of the external IO components. It requires userspace configuration utility - though. - - DST uses transaction model, when each store has to be explicitly acked - from the remote node to be considered as successfully written. There - may be lots of in-flight transactions. When remote host does not ack - the transaction it will be resent predefined number of times with specified - timeouts between them. All those parameters are configurable. Transactions - are marked as failed after all resends complete unsuccessfully; having - long enough resend timeout and/or large number of resends allows not to - return error to the higher (FS usually) layer in case of short network - problems or remote node outages. In case of network RAID setup this means - that storage will not degrade until transactions are marked as failed, and - thus will not force checksum recalculation and data rebuild. In case of - connection failure DST will try to reconnect to the remote node automatically. - DST sends ping commands at idle time to detect if remote node is alive. - - Because of transactional model it is possible to use zero-copy sending - without worry of data corruption (which in turn could be detected by the - strong checksums though). - - DST may fully encrypt the data channel in case of untrusted channel and implement - strong checksum of the transferred data. It is possible to configure algorithms - and crypto keys; they should match on both sides of the network channel. - Crypto processing does not introduce noticeble performance overhead, since DST - uses configurable pool of threads to perform crypto processing. - - DST utilizes memory pool model of all its transaction allocations (it is the - only additional allocation on the client) and server allocations (bio pools, - while pages are allocated from the slab). - - At startup DST performs a simple negotiation with the export node to determine - access permissions and size of the exported storage. It can be extended if - new parameters should be autonegotiated. - - DST carries block IO flags in the protocol, which allows to transparently implement - barriers and sync/flush operations. Those flags are used in the export node where - IO against the local storage is performed, which means that sync write will be sync - on the remote node too, which in turn improves data integrity and improved resistance - to errors and data corruption during power outages or storage damages. - - Homepage: http://www.ioremap.net/projects/dst - Userspace configuration utility and the latest releases: http://www.ioremap.net/archive/dst/ - -config DST_DEBUG - bool "DST debug" - depends on DST - ---help--- - This option will enable HEAVY debugging of the DST. - Turn it on ONLY if you have to debug some really obscure problem. diff --git a/drivers/staging/dst/Makefile b/drivers/staging/dst/Makefile deleted file mode 100644 index 3a8b0cf9643..00000000000 --- a/drivers/staging/dst/Makefile +++ /dev/null @@ -1,3 +0,0 @@ -obj-$(CONFIG_DST) += nst.o - -nst-y := dcore.o state.o export.o thread_pool.o crypto.o trans.o diff --git a/drivers/staging/dst/crypto.c b/drivers/staging/dst/crypto.c deleted file mode 100644 index 351295c97a4..00000000000 --- a/drivers/staging/dst/crypto.c +++ /dev/null @@ -1,733 +0,0 @@ -/* - * 2007+ Copyright (c) Evgeniy Polyakov <zbr@ioremap.net> - * All rights reserved. - * - * This program is free software; you can redistribute it and/or modify - * it under the terms of the GNU General Public License as published by - * the Free Software Foundation; either version 2 of the License, or - * (at your option) any later version. - * - * This program is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
