The SAN is a common component in many customer issues. To illustrate, we'll use an actual support case without names. In this example, we were seeing terrible performance from the test host.

Latency varied wildly, with several hundred milliseconds of peak latency. Make sure you know the topology. Please consult with your switch vendor's documentation on how to confirm your topology.

These systems commonly have a number of bladed servers that connect to an embedded switch over a copper bus. For example, a bladed chassis might have 16 discrete servers.

Each of these servers connects to an internal HBA which connects to the embedded switch. These will log into a core switch passing frames over to storage. The oversubscription rate can get quite high if you use a hypervisor for your discrete servers.

Add Virtual Machines to each blade, let's say 4 VMs per blade, and what do we end up with? On an 8Gb switch, this is eight hosts for each 8Gb port. For daily operations, this is usually fine, but if you have several high demand systems on this chassis; a database, development systems, this configuration can behave like a bottleneck.

This is the driving force behind 16Gb Fibre Channel and the coming 32Gb standard. This configuration is particularly devastating for iSCSI. Any time a number of links transmitting near capacity are switched to a smaller number of links, such oversubscription is a possibility. Recovering from these dropped network packets results in large performance degradation.

In addition to time spent determining that data was dropped, the retransmission uses network bandwidth that could otherwise be used for new transactions. Be aware that with software-initiated iSCSI and NFS the network protocol processing takes place on the host system, and thus these might require more CPU resources than other storage options.

In other words, err on the side of too much bandwidth instead of too little. Assuming that you have plenty of network ports, please do avail yourself of all of Pure's ports. You will need to make sure that you balance between maximizing connections to the Pure Storage FlashArray, and any host limitation you may have on the number of connections.The all-flash storage pioneer confirmed it enacted a round of layoffs this week as part of a strategic "rebalancing" of its workforce.

The cuts come on the heels of strong sales. According to its latest securities filing, Pure ended the Jan. The vendor has been adding new salespeople in the last year in an effort to widen market share in external storage systems.

SAN Guidelines for Maximizing Pure Performance

The Pure Storage layoffs will "align our employees with company priorities and areas that are strategic to the business," the company said in a statement. Job cuts have swept across Silicon Valley in recent weeks. Semiconductor maker Marvell slashed about jobs in January.

Google Cloud laid off 50 people and VMware jettisoned more than employees. Analysts say Pure's cautious stance reflects industrywide concerns stemming from China's economic slowdown and worsening fears over the new coronavirus. In Pure's case, the guidance is still pretty strong for the rest of the year.

I'd be more worried if Pure Storage announced layoffs and revised guidance. That would send a bad message," McDowell said. Pure is encouraging its laid-off employees to apply for other jobs in the company and has set up support for people to make career transitions. Please check the box if you want to proceed.

Upon rebooting I suggest entering into the servers boot menu to select the USB device. Once the server has rebooted and the USB device selected a normal Windows Server setup process will begin.

After Windows Server completes the setup process then we can configure the install.

SANs were adopted to improve application availability and performance by segregating storage traffic from the rest of the LAN.

SANs enable enterprises to more easily allocate and manage storage resources, achieving better efficiency.

A SAN consists of interconnected hosts, switches and storage devices. The components can be connected using a variety of protocols. Fibre Channel is the original transport protocol of choice.

Another option is Fibre Channel over Ethernet FCoEwhich lets organizations move Fibre Channel traffic across existing high-speed Ethernet, converging storage and IP protocols onto a single infrastructure. Vendors offer entry-level and midrange SAN switches for rack settings, as well as high-end enterprise SAN directors for environments that require greater capacity and performance. At least one storage node must be connected to this network. SAN is associated with structured workloads such as databases, while NAS is generally associated with unstructured data such as video and medical images.

Unified storage — also known as multiprotocol storage — grew out of the desire to stop procuring SAN and NAS as two separate storage platforms and to combine unified block and file storage in one system. NetApp is generally credited with the development of unified storage, though many vendors offer multiprotocol options. Today, the majority of midrange enterprise storage arrays tend to be multiprotocol, Sinclair says.

Storage vendors continue to add features to improve scalability, manageability and efficiency. On the performance front, flash storage is having an impact on enterprise SANs. In the enterprise storage world, flash so far is making greater inroads in SAN environments because the structured data workloads in a SAN tend to be smaller and easier to migrate than massive unstructured NAS deployments.

What is in a SAN? What is unified storage?We were sad we were unable to meet with Alexandra during our time there, but we just had too much to do. There were no problems and we had a tremendous time. Thank you for a trip of a lifetime. I have already recommended you to a former colleague interested in a trip to Iceland and I am sure he won't be the last. I hope to get to use you again some day.

We started with the Full Circle tour and customized it. I've never used a tour company before--I do all the trip planning in our family, and even though we were using Nordic Visitor, I did a lot of research and had some specific requests. Larus was fantastic, answering my questions and making good suggestions about routes and places to stay. Nordic Visitor provides maps plus vouchers for all hotels, services, and tours booked through them.

Their road atlas is crammed with historical information. Unfortunately, it goes around the ring road in a clockwise direction, and we were going counter-clockwise--which meant I had to figure out how to read it backwards. Even if you're using Nordic Visitor to do your bookings, it's a good idea to take some responsibility for your trip and get a good guidebook or do some internet research before you go, especially if you want to look for small museums that don't make the "highlights" lists.

Nordic Visitor lends you a mobile phone, preloaded with minutes. Look up the roaming costs to use your own phone (assuming you've got a GSM phone) in Iceland, and you'll see what a good thing this is. We didn't use the phone a lot, but it was nice to know we had it, just in case there was a problem. Fortunately, we didn't need it. But again, it was nice to know it was there. We stayed in a an interesting variety of hotels (which I've reviewed), and got to see everything that we wanted to without feeling rushed to make the next stop.

It really was a perfectly planned trip. I like that the rental agency (Dollar Thrifty) includes a GPS. I had the map provided by Nordic Visitor, but the GPS was good for giv mark, United States Iceland Grand Tour, July 2013 Nordic Visitor terrific follow-up Overdue, however, we need to shout out to Sola at NV who really helped us all during our Grand (Self) Tour.
