IT Services Faster!

Most of us expect immediate delivery both as consumers and as employees. As employees, we are no longer willing to wait weeks for IT to deliver what we need. IT departments feel the pain that ensues from our urgency in the form of shadow IT.  Shadow IT results in the double trouble of higher risk and cost from a weaker ability to enforce compliance and best practices when users stray to acquire their own IT services.

What’s that? You believe if you add more staff to address this issue it goes away? You may provide more services but at the same slower pace while increasing operational costs and decreasing operating profits. The key to maintaining IT discipline and delivering services faster is simply a judicious use of integrated automation and management.  It dramatically increases your staff’s ability to execute quickly -- to IT standards.

Cisco UCS Director is that missing piece that your staff needs to deliver services faster.  It helps your staff deliver more services in minutes--not days or weeks.  It lets your staff spend time to align IT with the business, instead of manually spinning up systems--and that’s what we all want.

Cisco Achieves SAP HANA Certifications for Unified Computing Systems Mission-Critical Servers

Cisco Achieves SAP HANA Certifications for Unified Computing Systems Mission-Critical Servers

Cisco has received SAP HANA certification for its Unified Computing Systems (UCS) mission-critical servers with the Intel Ivy Bridge chip set.  All of these products are now listed on the Product Availability Matrix from SAP.  These servers will accommodate memory sizes from 128GB all the way to 2TB on the rack mount C460 M4.  A small 2T Scale OUT configuration can be implemented using 512G B260 servers with an external EMC VNX5400 persistant storage, and  up to 16TB can be achieved using the B460 or C460 models with EMC VNX5400 persistent storage.

Scaling NFV – The Performance Challenge

In the second part of my blog series I want to cover one of the main concerns that Services Providers are facing as they explore moving to NFV and that is performance and scalability. Common concerns I hear center around latency, throughput, queuing capabilities and security. These are valid concerns since SP’s have service level agreement (SLA’s) with the their customers which lead to penalties if performance drops below the SLA.  So will a virtualized network function perform at the same level as a purpose built networking device?

If you bundle it, they will come!

Recently I was speaking to someone (Mike from New Jersey) at Cisco Live and they were raving about their journey to the Flexpod. They were seeking the best compute, networking and storage yet didn’t want to be boggled down with details when it came to the purchasing process. Converged systems like this are relatively new, and honestly Read More »

Decoding UCS Invicta – Part 3

In part one of this series we covered the internals of HDDs, in part two we went over the internals of SSD, In part three we continue reviewing storage concepts to refresh or learn the right lingo.

Lets start by understanding “Redundant Array of Independent Disks” (RAID). There are RAID levels like RAID0 and RAID1 that are easily to understand and others like RAID5 and RAID6, which many sysadmins misunderstand.

Redundant Array of Independent Disks (RAID)

In the past RAID was also referred as a “Redundant Array of Inexpensive Disks”.  At the end of the day Read More »
