6 reasons to transition to IBM i Access Client (ACS)

Posted by Mark Rabin

9/9/16 3:20 PM

It has been a while since we last discussed the transition from IBM Client Access for Windows to IBM i Access Client Solutions. Since IBM recently added major enhancements to i Access Client Solutions (ACS) and Windows 10 is gaining wider acceptance, this is a good time to look at what’s new.

What You Need to Know About IBM's End of Service for IBM i 6.1 Announcement

Posted by Mark Rabin

9/17/14 7:30 AM

IBM has announced that September 30, 2015 will see the end of service for Version 6.1 of the IBM i Operating System and Licensed Programs. This aligns with IBM’s history of keeping two OS versions “active” at a time.  IBM will also withdraw support for DB2 Web Query version 1.1.x.  For clients needing support beyond that date, IBM plans to provide an option to purchase extended support.  We anticipate this will be similar to the support offering IBM currently provides for V5R4 clients.    

IBM i 6.1 became available in March of 2008.  At that time it was considered a significant step forward in functionality and performance.  6.1 brought us a number of technologies we now take for granted including, PowerVM, SSD’s, PowerHA, the web-based system console, encrypted backups and more.  This release also saw the change in naming from Version-Release to the more common “dot” system, i.e., Version 5 Release 4 to IBM i 6.1.  Since the advent of the Technology Refresh in IBM i 7.1, IBM is able to continue to add significant new functionality without the need for a new O/S version.  So we have seen the tradition of a new OS version every two years stretch to four years.  IBM i 7.1 has been available since March 2010 and IBM i 7.2 was released in June 2014.

IBM Announces the First POWER8-based Servers

Posted by Mark Rabin

4/29/14 8:50 AM

Yesterday, IBM announced the first server models based on the new POWER8 processor.  They are true game changers with chip-level optimization targeted at the demands of today’s business.  The POWER8 processors are the first chips ever designed to optimize analytics and big data.  They offer new levels of price/performance for cloud deployments.  These servers also deliver an open platform to deploy Linux from multiple vendors. At the same time, these servers provide significant performance gains for all IBM i, AIX and Linux applications.  The first five models to be announced are 2U and 4U servers with one and two processor sockets.  The larger “enterprise class” servers will be announced later in 2014.

Speaking of Linux, the open platform focus of this announcement is further supported by a new level of support for the open community.  IBM PowerKVM is a new open virtualization option for Linux Power systems built using Linux and KVM. Linux administrators will see the familiar interface for simplified virtualization management and operation.  This is an HMC-less option for Linux-only virtualized servers.  Ubuntu Linux Server is added to the previous Power server support from RedHat and SUSE.  Open Stack cloud framework integration is another example of the commitment to open computing.  The OpenPOWER Foundation has more than 25 partners (including Google, NVidia, Samsung and Micron) who will be bringing more innovation to Power technology in the coming months.

A New Generation of IBM Power Servers is Coming

Posted by Mark Rabin

I have been around IBM's Power Systems since 2001 when IBM unified the RS/6000 and the AS/400 onto POWER4 and I have seen the Power platform continue to evolve. In my opinion the latest evolution looks to be a significant step forward, even as the Power7+ processor still outperforms many competing platforms.

Storage Optimization Made Easy with IBM Real-time Compression and Easy Tier

Posted by Mark Rabin

1/24/14 11:00 AM

Statistics about disk storage growth are everywhere. 

Depending on who you're talking to you might hear “Global disk storage is growing 40 percent per year” or “Enterprise disk demand is increasing by 50 percent per year.”  Well in the real world of our clients the number may not be quite that high, but it is certainly growing in the double digits.  While the cost of technology keeps dropping, the cost of storage is still increasing as capacity growth demands exceed price reductions.  And the energy costs of storage are not to be discounted.  To get a clear idea of cost start with the price of the disk drive, add in housing the drive (in a storage array or SAN), then add maintenance, energy costs to run and cool the drive, and it adds up quickly.  The fully loaded cost of a disk drive could be around $1,500 to more than $3,000 per drive over a 3 year period. 

 

What if you could store three to five times as much data on each disk drive?

Mid-Market Storage Wars

IBM V5000 vs. EMC VNX2… the TamGroup Perspective

September and October 2013 have seen major announcements from EMC and IBM respectively in the mid-market storage space. Where IBM has announced major extensions to their industry-leading technology of Storwize family products, EMC announced a warmed-over refresh of their VNX series, the VNX2.

The new IBM V5000 provides a mid-market Storwize platform for customers looking for a more cost-effective SAN than the V7000. The V5000 utilizes the same virtualized storage platform that is the hallmark of the IBM Storwize family but only supports a maximum of 168 drives per controller/336 per cluster.  With standard support for 1GB/10 Gb iSCSI, 6Gb SAS, 8GB FC and 10Gb FCoE, it provides flexible connectivity for most environments in a small 2U rack footprint.  The V5000 can virtualize and seamlessly migrate storage from other SAN platforms making transitions from competitive products easy and cost effective.  The inclusion of SANSlide compression over TCP/IP in the optional remote replication feature means DR implementations will use less bandwidth than ever before.

IBM PureSystem – The first expert integrated system infrastructure

Posted by Mark Rabin

4/11/12 4:26 AM

Simplified deployment and management of servers, networks, storage and virtualization has been trumpeted by many vendors for their products.  In some cases they delivered that capability for their respective products, but not the entire infrastructure.   In an industry first, IBM is delivering integrated management for the complete infrastructure stack in the next generation platform called IBM PureSystem.  This Expert Integrated System has captured the experience of thousands of server, network, storage and virtualization deployments and merges it into a single management interface, the IBM Flex System Manager.

We recently went through an elaborate sizing exercise with IBM Techline for WebSphere Commerce for a client that was evaluating their e-commerce platform and strategy.  As is the norm, cost mattered, and the default assumptions baselined Linux and hypervisor on an Intel platform.
