Nexsan’s Flexible Storage Platform – A New Experience

Yesterday i came across to this product and seems to be a great one!!! Nexsan is first to ship enterprise- class storage systems with 3TB SATA drives for 180TB in 4U.

Nexsan’s Flexible Storage Platform enables many storage technologies to be incorporated in one system. This is particularly useful to mid-sized organizations that prefer a single-system solution over having to buy many disparate systems. Nexsan pioneered storage systems that featured simultaneous multi-protocol access, and we designed our systems to be multi-tiered, supporting high-speed and high-cost SSD, mid-speed and mid-cost SAS and low-speed and low-cost SATA drives in one chassis. Our flexible storage platform supports our proprietary storage applications software, such as replication, de-duplication, data archiving, multi-tenancy, digital data backup and encryption. Nexsan’s industry-leading storage systems, the foundation of the Flexible Storage Platform™, contain anywhere between 14 and 60 drives and can be expanded with an additional expansion unit. Drives benefit from Nexsan’s Anti-vibration Design™, Cool Drive Technology™ and Active Drawer Technology™. All Storage Systems can be configured with dual active/active controllers with battery-backed cache for high throughput and no-single-point-of-failure architecture through the Fibre Channel and/or iSCSI host access ports for block services, or via LAN for file services.

Key Benefits

  • Offers SATA, SAS or SSD disk combinations
  • Highest density per rack inch with 60 disks in a 4U chassis
  • 180TB capacity in 4U
  • Three active drawers for easy servicing
  • Anti-vibration design maximizes disk reliability
  • AutoMAID® level 4 reduces energy consumption by 85%
  • Horizontal mid-plane maximizes airflow and cooling

Microsoft iSCSI Software Target 3.3

The Microsoft iSCSI Software Target 3.3 provides storage (disks) over a TCP/IP network. It turns a computer running Windows Server into a storage device which provides shared block storage. iSCSI Software Target is an optional Windows Server component that provides centralized, software-based and hardware-independent iSCSI disk subsystems in storage area networks (SANs). One scenario involved using Microsoft  iSCSI Software Target in a “two-node Failover Cluster,” with 92  Hyper-V virtual machines storing data to one of the nodes. Finally, Microsoft iSCSI Software  Target 3.3 supports the remote booting of diskless computers “from a  single operating system image using iSCSI.”

You can use Microsoft iSCSI Software Target 3.3 to perform a variety of storage-related tasks, including the following:

  • Provide shared storage for Hyper-V to enable high availability and live migration
  • Consolidate storage for multiple application servers (i.e. Microsoft SQL Server or Hyper-V)
  • Provide shared storage for applications hosted on a Windows failover cluster
  • Enable diskless computers to boot remotely from a single operating system image using iSCSI

The Microsoft iSCSI Software Target 3.3 is an economical solution suited for a development or test environment and a small, medium, or branch office production environment. It enables storage consolidation and sharing on a Windows Server by implementing the iSCSI (Internet Small Computer Systems Interface) protocol, which supports SCSI-block access to a storage device over a TCP/IP network.

To download The Microsoft iSCSI Software Target 3.3, click here. Microsoft is recommending using Service Pack 1 with Windows  Server 2008 R2 for this release of Microsoft iSCSI Software Target. The product  can be installed in a Hyper-V virtual machine. It doesn’t work with a core  installation of Windows Server 2008 R2.

Dell MD3000i SAN – 2 Disk failure scenario

If you have a 2 disk failure scenario on an MD3000i iSCCI SAN storage from DELL, Do not worry, because the internal firmware of the RAID takes care, even if the Hotspare disk gets failed. Here is a typical scenario, which happened to me where, DISK 9 gets failed and at the same time HOTSPARE disk also failed. Thanks to DELL support team. You have to notice one thing that when you replace the disk, first replace the DISK 9 with the new one and the SAN rebuild the data automatically and once you get the status as “Optimal”, you then replace the HOTSPARE disk with new one.

Enjoy!!!

Windows server 2008 to 2008 R2 upgrade – need to know

When you upgrade your server from Windows server 2008 to Windows server 2008 R2 upgrade, make sure that you write down all the IP’s related to each port, include SAN IP’s using iSCSI. The reason its because after you upgrade to Windows Servr 2008 R2, all the IP you setted up manually for the system, no matter whether it is local ip or SAN ip will be resetted and you have to do it manually again.

This is for your information that you should take a screen shoot or write it manually somewhere.
