In computing, iSCSI is an acronym for Internet Small Computer Systems Interface, an Internet Protocol -based storage networking standard for linking data storage facilities. It provides block-level access to storage devices by carrying SCSI commands over a TCP/IP network. ISCSI is used to manage storage over long distances, it can be used to transmit data over local area networks, wide area networks, or the Internet and can enable location-independent data storage and retrieval. The protocol allows clients to send SCSI commands to storage devices on remote servers, it is a storage area network protocol, allowing organizations to consolidate storage into storage arrays while providing clients with the illusion of locally attached SCSI disks. It competes with Fibre Channel, but unlike traditional Fibre Channel which requires dedicated cabling, iSCSI can be run over long distances using existing network infrastructure. ISCSI was pioneered by IBM and Cisco in 1998 and submitted as a draft standard in March 2000.
In essence, iSCSI allows two hosts to negotiate and exchange SCSI commands using Internet Protocol networks. By doing this, iSCSI takes a popular high-performance local storage bus and emulates it over a wide range of networks, creating a storage area network. Unlike some SAN protocols, iSCSI requires no dedicated cabling; as a result, iSCSI is seen as a low-cost alternative to Fibre Channel, which requires dedicated infrastructure except in its FCoE form. However, the performance of an iSCSI SAN deployment can be degraded if not operated on a dedicated network or subnet, due to competition for a fixed amount of bandwidth. Although iSCSI can communicate with arbitrary types of SCSI devices, system administrators always use it to allow servers to access disk volumes on storage arrays. ISCSI SANs have one of two objectives: Storage consolidation Organizations move disparate storage resources from servers around their network to central locations in data centers. In a SAN environment, a server can be allocated a new disk volume without any changes to hardware or cabling.
Disaster recovery Organizations mirror storage resources from one data center to a remote data center, which can serve as a hot / standby in the event of a prolonged outage. In particular, iSCSI SANs allow entire disk arrays to be migrated across a WAN with minimal configuration changes, in effect making storage "routable" in the same manner as network traffic. An initiator functions as an iSCSI client. An initiator serves the same purpose to a computer as a SCSI bus adapter would, except that, instead of physically cabling SCSI devices, an iSCSI initiator sends SCSI commands over an IP network. An initiator falls into two broad types: A software initiator uses code to implement iSCSI; this happens in a kernel-resident device driver that uses the existing network card and network stack to emulate SCSI devices for a computer by speaking the iSCSI protocol. Software initiators are available for most popular operating systems and are the most common method of deploying iSCSI. A hardware initiator uses dedicated hardware in combination with firmware running on that hardware, to implement iSCSI.
A hardware initiator mitigates the overhead of iSCSI and TCP processing and Ethernet interrupts, therefore may improve the performance of servers that use iSCSI. An iSCSI host bus adapter implements a hardware initiator. A typical HBA is packaged as a combination of a Gigabit Ethernet network interface controller, some kind of TCP/IP offload engine technology and a SCSI bus adapter, how it appears to the operating system. An iSCSI HBA can include PCI option ROM to allow booting from an iSCSI SAN. An iSCSI offload engine, or iSOE card, offers an alternative to a full iSCSI HBA. An iSOE "offloads" the iSCSI initiator operations for this particular network interface from the host processor, freeing up CPU cycles for the main host applications. ISCSI HBAs or iSOEs are used when the additional performance enhancement justifies the additional expense of using an HBA for iSCSI, rather than using a software-based iSCSI client. ISOE may be implemented with additional services such as TCP offload engine to further reduce host server CPU usage.
The iSCSI specification refers to a storage resource located on an iSCSI server as a target. An iSCSI target is a dedicated network-connected hard disk storage device, but may be a general-purpose computer, since as with initiators, software to provide an iSCSI target is available for most mainstream operating systems. Common deployment scenarios for an iSCSI target include: In a data center or enterprise environment, an iSCSI target resides in a large storage array; these arrays can be in the form of commodity hardware with free-software-based iSCSI implementations, or as commercial products such as in Quantastor, CloudByte, StorTrends, Pure Storage, HP StorageWorks, EqualLogic, Tegile Systems, Nimble storage, Reduxio, IBM Storwize family, NetApp filer, Dell EMC, Kaminario, NS-series, CX4, VNX, VNXe, VMAX, Hitachi Data Systems HNAS, or Pivot3 vSTAC. A storage array provides distinct iSCSI targets for numerous clients. Nearly all modern mainstream server op
Téviec or Théviec is an island situated to the west of the isthmus of the peninsula of Quiberon, near Saint-Pierre-Quiberon in Brittany, France. The island is an important archaeological site due to its occupation during the Mesolithic period. Many archaeological finds have been made dating back to over 6,700 years before the present day, including the remains of over 20 people. One of the most remarkable finds was that of the grave of two young women who had died violently but had received an elaborate burial under a "roof" of antlers, their bodies decorated with jewellery made from shells. Téviec is owned and since 12 January 1982 it has been the subject of a biotope protection scheme, which aims to preserve important biotopes. Landing on the island is prohibited from 15 April to 31 August. From 1928 to 1934, archaeologists Marthe and Saint-Just Péquart discovered and excavated a range of Mesolithic habitats and a necropolis of the same period; the island is one of only a few known Mesolithic sites in Brittany, along with Pointe de la Torche, Hoëdic and Beg er Vil on the Quiberon peninsula.
During the Mesolithic period, the sea level was much lower – it was possible to walk from France to England – and Téviec was situated in a lagoon. Extensive middens were found near places of habitation on the island, containing the remains of shellfish, squid, birds and terrestrial mammals including wild boar, red deer, roe deer, dogs and so on; the hunter-gatherers of Téviec buried their own dead in the middens. This helped to preserve the graves, as the carbonates from the shells in the middens insulated human bones from the acid soil. Many tools made of bone and antler were found along with numerous flint microliths, they were believed to date to 6575 years BP but have now been dated to between 6740 and 5680 years BP. This indicates a longer occupation than thought, with its end coming at the beginning of the Neolithic period. Ten multiple graves were discovered at Téviec containing a total of 23 individuals, including adults and children; some of the remains were scattered between different locations.
Several of those interred appear to have died violent deaths. One individual was found to have a flint arrowhead stuck in a vertebra. In another grave, the skeletons of two women aged 25–35, dubbed the "ladies of Téviec", were found with signs of violence on both. One had sustained five blows to the head, two of which would have been fatal, had received at least one arrow shot between the eyes; the other had traces of injuries. However, this diagnosis is disputed by some archaeologists, who have suggested that the weight of earth above the grave may have been responsible for damaging the skeletons; the bodies had been buried with great care in a pit, dug into the ground and covered over with debris from the midden. They had been protected by a roof made of antlers and provided with a number of grave goods including pieces of flint and boar bones, jewellery made of sea shells drilled and assembled into necklaces and ringlets for the legs; the grave assemblage was excavated from the site in one piece and is now on display at the Muséum de Toulouse, where its restoration in 2010 earned a national award

Cannabis in Georgia is illegal for recreational use, but decriminalized in the cities of Atlanta, a few others. Limited medical use is allowed in the form of cannabis oil containing less than 5% THC. In the 1970s and 1980s, a number of county sheriffs and deputies were prosecuted for their involvement in the drug trade, including Sheriff John David Davis, a former moonshiner, pardoned by President Nixon and was convicted in 1984 of smuggling cannabis into south Georgia. Davis' case parallels that of a number of other former moonshiners who segued into the cannabis trade. In 1983, amidst controversy, the Drug Enforcement Administration conducted aerial spraying of illegal cannabis plots in the Chattahoochee National Forest in northern Georgia, using the herbicide paraquat. Citizens and a congressman objected, noting paraquat's dangers, a temporary restraining order was placed on further spraying; the federal Drug Abuse Policy Officer Pat McKelvey rebutted that paraquat is a safe and used herbicide, alleged that the objections to the DEA spraying had been raised by cannabis growers and legalization advocates.
In February 1980, a 50-0 Senate vote and a 156-8 House vote passed Mona Taft's bill supporting legal medical marijuana in Georgia for people diagnosed with glaucoma and cancer patients undergoing chemotherapy and radiation. Members from both parties came together to support Taft, including then-state Sen. Paul Broun. According to a Feb. 14, 1980, Knight-Ridder wire report about the bill, Broun hugged Taft when the legislation passed the Senate. The bill's sponsor, Rep. Virlyn Smith, R-Fairburn told the widow that he'd given a constituent taking chemotherapy a recipe for marijuana-laced chocolate-chip cookies. Georgia's program had ended without supplying a single patient with the medical marijuana promised. Subsequent Georgia governors had the authority to reappoint the board, but never acted; as a result, the law has lingered on the books for the last 30 years. A measure to allow medical cannabis oil up to 5% tetrahydrocannabinol passed the Georgia House in February 2015. On April 16, 2015, the low-THC cannabis oil was legalized for medical use in the state under HB 1, the Haleigh’s Hope Act.
The bill was enacted after being signed by Governor Nathan Deal. The bill allowed possession of the oil for eight qualifying medical conditions but did not provide for cultivation or distribution within the state. A May 2017 expansion under SB 16 added six more conditions. In 2018, HB 65 added posttraumatic stress disorder. In April 2019 legislation was approved to allow in-state cultivation of cannabis and sale of the low-THC oil. Medical cannabis was not without precedent in Georgia. In October 2017, Atlanta City Council voted 15–0 to reduce the penalty for up to one ounce of cannabis to a $75 fine. Savannah City Council followed in March 2018 by voting 8 -- 1. Other jurisdictions that have decriminalized or otherwise acted to reduce penalties include: Clarkston, South Fulton, Forest Park, Statesboro, Macon-Bibb County, Chamblee
