KernSafe adds support for Snapshot feature in iStorage Server 2.30

Full support for Snapshot in native versions x32, x64 and Itanium of iStorage Server.

February 28, 2011 - KernSafe Technologies Inc., A world leader in security storage and iSCSI solution, announced today a release of iStorage Server version 2.30 with support Snapshot feature.

Snapshot is the state of a system at a particular point in time. It refers to an actual copy of the state of a system. Snapshot feature is especially valuable in High-Availability clusters because they cannot bear service stoppages. To avoid downtime, high-availability systems may instead perform the backup on a snapshot—a read-only copy of the data set frozen at a point in time—and allow applications to continue writing to their data. In other words, the time needed to create the snapshot does not increase with the size of the data set, whereas the same for a direct backup is proportional to the size of the data set. In some systems once the initial snapshot is taken of a data set, subsequent snapshots copy the changed data only, and use a system of pointers to reference the initial snapshot. This method of pointer-based snapshots consumes less disk capacity than if the data set was repeatedly cloned. Previous versions of iStorage server were supporting only VHD image files that were limited to 2040GB according to their specifications. Now iStorage Server supports Standard Image File (IMG Files) that don’t have any size limitation, user can create as big image file as he wants to.

iStorage Server is an iSCSI target software which makes any x86, x64 or even Itanium Windows server into a high performance iSCSI SAN. Being an advanced and powerful, full-featured iSCSI Target software for Microsoft Windows (both commercial and free versions are available), it allows you quickly export existing storages such disk images, physical disks, partitions, CD/DVD-ROMs, tapes or any other type of SCSI based devices and even a variety of popular CD/DVD images to its client machines, which delivers immediate benefits allowing storage to be consolidated, virtualized and centrally managed. iStorage Server has also provided RAID-1 (mirror) feature, which allows you create two iSCSI devices for mirror backup, the iSCSI device can be local image file or remote iSCSI device, also with new added support for High-Availability and snapshot feature it is an ideal choice for any sized business.

iStorage Server is a hardware-independent, and do not require an additional hardware. Quickly create an IP SAN in minutes using hardware you already have. iStorage Server takes space on a windows file system and turns it into an iSCSI target. You can now let any computer on an Ethernet network use this iSCSI storage with benefits of cost-effective and scalable.

KernSafe has devoted to research storage solution for more than eight  years, and which always trying their best to make and meet a variety of user needs, from now on, iStorage Server has been released more than 2 years, and been sold more than 2000 copies of commercial versions. iStorage Server now supports natively x86 and x64, as well as Itanium machines.

Typical applications & clients:

•    Files, disks and CD-ROMs (images) centrally management and sharing to other Windows, Linux, Solaris, Netware and MACOS computers.
•    VMWare ESX Server
•    Citrix XenServer
•    Microsoft Hyper-v.
•    Windows 2003, Windows 2008 Clustering and more.

iStorage Server Key Features:

•    Provides extremely fast ISCSI RAM disk drives for temporary data storing on network.
•    Provides security disks for each client, Option, each client use own disk which use it’s CHAP password encrypted.
•    Provides a built-in iSCSI CD/DVD-ROM emulator which exports existing DVD-ROM ISO images to mounted iSCSI DVD-ROM drives on the clients.
•    Provides a built-in iSCSI virtual disk emulator. It exports existing disk images to mounted iSCSI disk drives on the clients.
•    Provides a network-bridged method. It exports an existing partition, disk, CD/DVD-ROM to clients as a virtual iSCSI drive.
•    Provides a RAID-1 (Mirror) device, it allows you create two image files for mirror backup, image file can be local file or remote iSCSI device.
•    Provides Generic SCSI device, it allows you map generic SCSI devices to your initiator, such as USB Storage, Tape and Optical Scanner.
•    Provides read and write caching, which use memory on server as cache to improve data transfers speed and response time.
•    Provides CHAP user authentication mechanism.
•    Provides client's IP address authentication mechanism with additional security.
•    Active Directory-integrated local and remote management console.
•    Provides iSCSI Target portal address management, which allows you to make iStorage Server to be able to work behind the firewall.
•    No restrictions on disk capacity, total number of hard disk installed, number of CPUs or CPU cores, and Ethernet ports or the amount of RAM.
•    Supports CDP/Snapshots, is compatible with Microsoft VSS (Volume Shadow Copy Services) snapshot, volume cloning and incremental backups with unlimited number of rollback points.
•    Supports High-Availability implementation of technology.
•    Supports multiple connections per iSCSI session, which allows you to create Round Robin, Weighted Paths and so on.
•    Native supports for x86, x64 and Itanium machines.
•    Supports Thin provisioning.
•    Supports 64-bit LBA, providing more than 2TB of disk space.
•    Supports sparse image file on NTFS file system. It allows the size of disk image file only depend on its content used.
•    Supports any features on file system, such as in NTFS, a image file can be encrypted, compressed, or shared with other computers.
•    Supports a variety of popular CD/DVD image formats, such as: .iso, .bin, .mdf, .cdi, .b5i, .nrg, .ccd, .sub, .img, .raw.
•    Supports a variety of partition table format, such as the MBR, GPT.
•    Fully Supports SCSI-2 Reserve / Release.
•    Fully Supports SCSI-3 Persistent Reserve.
•    Fully conforms to the latest iSCSI Standard 1.0 (former Draft 20).
