EqualLogic’s new 10GbE iSCSI SAN now with 10X more storage performance for virtualization & high throughput business applications.
The newest iSCSI arrays in the PS Series, the EqualLogic PS6010 and PS6510, add the power of 10GbE technology to the exceptional EqualLogic storage performance of previous generations. They deliver increased bandwidth performance for streaming workloads, business critical applications, virtualization, storage consolidation and high-volume data backup and data protection.

The majority of customers I work with today do not have centralized storage, a SAN, today. The customers environment looks like Figure 1 below, which we refer to as Direct Attached Storage, or DAS. You have a number of servers that have internal disk and at least a single NIC that connects the server to the LAN. My post below discusses performance and capacity concerns when you have servers running DAS.
Figure 1
In moving to a SAN your servers have 2 more additional NICs that will connect to dedicated Gigabit Ethernet Switches and also connect to your EqualLogic PS Series Array. This creates a Highly Available SAN so you can lose a NIC, a cable, a switch, an EqualLogic Controller and your SAN is still up and running without downtime.
This is a SAN, your storage area network, that is dedicated to centralizing your storage. By creating a centralized pool of storage you are now able to provide performance and capacity “on the fly” to your applications. Figure 2 below is an example of what a SAN with an EqualLogic PS Series Array looks like.
Figure 2
Figure 3 below illustrates creating a Volume from an EqualLogic Storage Pool and connecting that to Server One as Drive E: and Drive F:. iSCSI is simply scsi/disk commands over gigabit Ethernet. Server One views Drive E: and Drive F: as local hard disks that you just placed into your physical server.
Figure 3
With EqualLogic PS Series Arrays, you can setup your SAN in under an hour which will give your servers and applications additional capacity and performance when needed without interruption or downtime.

Limited capacity
Your server has only so many slots/bays for hard drives. Sometimes when you are looking at a server the first spec you review is simply how many hard drives can this server hold? Many of your servers are now 3 to 5 years old and there is nothing more you can do to add capacity because there are no more slots/bays left for hard drives. Hopefully you haven’t reached the point of coming in early in the morning before everyone else just to delete files so you can make it through another day.
Investing in and connecting your servers to an EqualLogic array will provide extremely scalable capacity for your servers. Looking forward, your next server purchase will not have to be based on how many slots/bays are available so long term you can spend less on your servers.
Limited performance
The limited slots/bays for hard drives on your server not only limits capacity, performance can also be extremely limited. You have a server with 6 drive slots/bays and you purchase 6 hard drives. Two of the hard drives will be mirrored, configured as RAID1, for the Operating System. Four of the hard drives will be configured as RAID5 for application and data. If you are running Exchange or SQL on this server you may find that you have plenty of capacity available, however the application performance is lagging and getting worse every week.
Investing in and connecting your servers to an EqualLogic array can provide additional performance for your application that was constrained to the performance limits, number of hard drives, inside of your server.
If you are a Server/Network/Systems Administrator and you have limited or no SAN experience, be not afraid. EqualLogic is an easy to use, highly scalable, with all inclusive software and management, SAN solution that will relieve your server capacity and performance problems.
