IBM #XIV introduces Real-time Compression

Last week IBM made a significant announcement on XIV Gen3 : ' IBM XIV Storage System Gen3 and IBM XIV Cloud Storage for Service Providers V11.6.0 deliver support for IBM Real-time Compression and disaster recovery with Microsoft Azure Site Recovery (ZP15-0250)'.

Highlights
I think the real eye-catcher over here is the introduction of Real-time Compression. This is reflected in the overview of what's announced :
  • IBM Random Access Compression Engine (RACE) technology without need for extra hardware to scale performance and simplify compression management
  • Increased usable capacity per rack to lower cost per capacity
  • Faster replication of compressed data using less bandwidth to free up bandwidth for other uses
  • Continuous display of predicted or actual compression ratios for all volumes to increase performance
  • Nondisruptive conversion of uncompressed volumes to compressed volumes for faster data mobilization
  • Support for Microsoft™ Azure Site Recovery to seamlessly manage XIV replication for Microsoft infrastructures
Double your capacity ?
What does this mean in terms of usable capacity. Well : here's the maximum capacity for an XIV with 180 disks and disks of 1TB/2TB/3TB/4TB/6TB : 80TB/161TB/243TB/325TB/485TB (decimal TB that is). The announcement says this will "increase usable capacity per rack typically to one petabyte or more with IBM Real-time Compression™ (using a 15-module system with 6 TB disk drives)". Of course, as always, results will vary, but let's say capacity could be doubled with this inline compression.

Requirements/limitations
"IBM Real-time Compression is a software license option that is only available for XIV Gen3 systems, including models 114 and 214, with XIV software V11.6.0, on new systems, or as an MES upgrade". "Compression is applied to individual volumes and snapshots. There is no limit however on the amount of usable capacity that is subject to compression. Compression need to be system-enabled before it can be applied to individual volumes. Mirroring requires that both primary and secondary volumes are compressed".

Trial
"IBM is offering current IBM Storage XIV Gen3 customers the opportunity to evaluate the new Real-time Compression capability at no cost for 45 days. (...) The 45-day evaluation period begins when the XIV Real-time Compression function is enabled. At the end of the evaluation period, customers must either purchase the required licenses for Real-time Compression or disable the function".

Pricing
Did I see the word "purchase" over there ? Yes, Real-time Comrpession seems to be the first license on the XIV that does not come for free with the box. I must say that for the moment I haven't got any clue about the price setting of this feature. 

Redbook
There's a nice little Redpaper called 'IBM Real-time Compression on the IBM XIV Storage System' available on the Redbooks site.

Planned Availability  is June 4, 2015.

IBM announcement : DS8870 enhancements

Here's another announcement from last week specifically for the DS8870, the latest generation of the DS8000 : ' IBM DS8870 delivers expanded connectivity and extends cloud enablement support with z Synergy for integration of z Systems and Storage systems (ZG15-0098)'.
Availability date is May 22, 2015 and all "announced features and functions are supported on the IBM System Storage® DS8000 series and require DS8000 LMC 7.7.50.xx.xx (bundle version 87.50.xxx.xx), or later".

Here's an overview of the new features :

16GFC FC/FICON connectivity:
DS8870 supports 16GFC FC/FICON connectivity with an optional four-port host adapter card. Model 961 supports four adapter card pairs and Model 96E supports four additional adapter card pairs, enabling a total of sixty-four 16GFC FC/FICON ports.

New and improved z Synergy features:
  • FICON® Dynamic Routing: This feature supports Systems Business Class and Enterprise Class models and enables use of dynamic routing policies for cascaded directors in the SAN. Examples of dynamic routing policies include Brocade Exchange Based Routing (EBR) or Originator Exchange ID Load Balancing (OxID) across cascaded FICON Directors. The value of FICON Dynamic Routing is to help reduce cost by allowing Metro Mirror and FICON traffic to share the same set of ISLs. This can help reduce the number of ports required, fibers, and intercite bandwidth.
  • Forward error correction (FEC): This feature helps to correct I/O errors and improve the reliability of 16 Gbs links, encouraging the adoption of faster link speeds. This feature also protects DS8870 Metro Mirror links connected to 16GFC host adapters and FCP links connected to switches that support standard FEC negotiation protocols.
  • zHPF Extended Distance II: This feature delivers better zHPF large block write performance at longer distances (up to 100 Km) and improved FC fabric congestion management.
  • Fabric Priority for FICON, zHPF, and FCP: z Workload Manager (zWLM) will assign a fabric I/O priority for every I/O operation executed by z/OS® thus extending the scope of management into the SAN. The DS8870 exploits fabric priority by propagating it to the Metro Mirror traffic generated for write requests and by echoing back the priority to get the value on read requests. Fabric priority complements the FICON Dynamic Routing feature by insuring the FICON traffic and the Metro Mirror traffic are managed to a consistent set of policies.
  • Read Diagnostics Parameters (RDP) support: RDP enables new standard link services for obtaining diagnostic information including link speeds and power levels from FC end points and switch ports to aid in link fault isolation.
Heat Map Transfer for MGM environments:
With this release, heat map transfer supports MGM replication topology in addition to Metro Mirror/Global Copy/Global Mirror (MM/GC/GM) functions.

REST API:
This release includes support for monitoring, configuring, and controlling aspects of the DS8870 system configuration by use of an industry-standard REST API.

Performance monitoring:
The improved DS8000® Storage Management GUI provides system performance monitoring in real time. A storage administrator can view performance metrics from up to one week earlier down to one minute intervals in order to troubleshoot a wide variety of issues. Supported graphs include the following:
  • I/O, bandwidth, caching, capacity, and power/temperature monitoring at a system level
  • Back-end I/O, back-end bandwidth, and capacity monitoring at a pool level
  • Front-end I/O and bandwidth monitoring at a pool level

Simplified encryption setup:
The improved DS8000 Storage Management GUI also provides simplified encryption setup and management through a simplified encryption paradigm matching other products. This enables a storage administrator to configure encryption within five minutes of finishing system setup.

New series of z13 videos on Youtube

I picked this up via the IBM-Main list (thanks to John McKnown) : it's a five video series on the new IBM z13 system by Jeff Frey, IBM Fellow and z Systems CTO. They are really worth a look and explain each time in about 4 minutes an aspect of the value of the new IBM z13. I really enjoyed them.

A teaser ?
"Some people have the perception that because the architectural routes of this platform are fifty-years-old that it's an old system. It has some of the most modern technology of any commercial server in the industry"
Or
"You know one of the best-kept secrets I think of the z system is its ability to process large amounts of sustained performance in terms of I/O both storage and network and I think it contributes greatly to the economic value of the platform"

The five videos treat :
  • An IBM z13 introduction and technical overview (link) (This link starts the entire series)
  • The IBM z13-a well-balanced system for I/O and processing (link)
  • Efficient analytics on the IBM z13 (link)
  • Workload efficiency on the IBM z13 (link)
  • Linux, KVM and the Cloud on the IBM z13 (link)
 As I always say, just check them out !

Introduction to the value of IBM XIV - a RealDolmen publication

I already told you about our XIV Roundtable event on Tuesday 2, 2015 but we also took some other initiatives to put IBM XIV into the spotlights.

One of those was composing an introductory brochure to XIV and particularly to the value of XIV for your business.  It was a challenging but rewarding effort, summarizing lots of presentations, studies, white papers and so forth into a 24-page brochure. But I think we came out with a great result. As you can see, we grouped everything around six themes : Elasticity, Security&Continuity, Efficiency, Manageability, Performance and Out-of-the-box Integration. 


But bottom line, you know, is most of the time the impact all this has on the cost for your business and we also payed quite some attention to this.

If you want to download this brochure, you can find it via the registration page of the Roundtable event over here : 'Powerful storage with IBM XIV'.

Price Changes on Selected System z and zSeries Software Program Products

Well, after more than a month of silence, I'm back on my feet. I had to undergo some surgery but I've recovered well and I'm back at work. I have to wait another couple of weeks before I can start running again, but the doctor says that blogging is quite OK ;-) . So here we go again.

I'm starting off with mentioning a couple of announcements from the last month and here's the first one : 'Price Changes on Selected System z and zSeries Software Program Products (ZA15-1111)'. There's a price increase in one-time charges (OTC) and associated Subscription and Support (S&S) recurrent license charges (monthly and annually). If you have a look at the list, it's all Websphere products.

The price increases (if any) vary from country to country. So you really have to take a look at the announcement for your own country. In Belgium it's an increase of 5%. Increased recurrent licence charges will be effective with the billing  period that starts on or after August 1, 2015. The one-time charge price increases are effective August 1, 2015.

Accelerate with ATS : What’s new with XIV - IBM Spectrum Accelerate

Here's another interesting webcast communicated via the Accelerate with ATS blog about XIV and its newly announced SDS version : IBM Spectrum Accelerate.

The webcast will focus on this IBM Spectrum Accelerate, "a software defined storage offering (...) based on our proven XIV integrated storage system. The same ease of management with the XIV GUI, the same hotspot-free performance, predictable scaling, enterprise capabilities such as remote mirroring and flash caching, and much more".

In short IBM Spectrum Accelerate is the very same software that runs on the XIV box, but as a customer you can (within some boudaries) decide which hardware you put underneath it. You get all the advantages and functionalities as with an XIV box, but you can create a smaller entry point starting from just a few x86 servers.

Let me give you some technical requirements :
Hardware requirements
x86 servers running VMware ESX Hypervisor with a VM configured according to the following specifications.

Minimal VM requirements:
CPU cores: 4 nonvirtualized CPU cores
Memory: 24 GB physical memory
Network: 2x 10 GbE ports
Disks: 6 to 12 hard-drives, 1, 2, 3, or 4 TB in size
SSD (optional): One 500 GB or 800 GB SSD

Recommended VM requirements:

Security Bulletin: Multiple vulnerabilities impact DS8000 HMC

Here's a new security bulletin on the DS8870 (and above). You can find it over here.
I'm not taking over all its content because it's a bit too elaborate but here's the summary

"Summary

There are multiple vulnerabilities in the DS8000 HMC which are covered in this bulletin and include the Padding Oracle On Downgraded Legacy Encryption (POODLE) SSLv3 vulnerability (CVE-2014-3566). This bulletin also covers several items which were updated to address other vulnerabilities.

Vulnerability Details


Before applying the patches or versions noted in this advisory, please read the additional notes - there are potential impacts to clients which connect to the updated servers since SSLv3 is disabled. You should verify that disabling SSLv3 does not cause compatibility issues.

While this advisory covers mainly CVE-2014-3566, product updates included also address the list of CVEs"
CVEs are concentrating on Open SSL, IBM Java and NTP.

Affected Products and Versions are DS8870 R7.2 and above, DS8800/DS8870 R6.3 SP 9 and above.

The fix is available as a full update as well as patch. You find all the necessary details in the bulletin itself.

Europe : 15% increase on all IBM System Storage hardware products

I overlooked this one as it was announced last Thursday instead of the regular Tuesday announcements. Perhaps Friday 13 would've been a better date for this announcement : 'Price changes: IBM System Storage hardware products (ZA15-1104)'. It's a short one, so I can keep it short too as I have no additional information about it either.
"IBM announces a 15% increase on all IBM System Storage hardware products."
This is applicable to Austria, Belgium, Cyprus, Germany, Denmark, Spain, Finland, France, Greece, Ireland, Italy, Netherlands, Norway, Portugal, Sweden, Slovenia, Slovakia and effective as of February 12, 2015.
For the UK it is only 10%.

I haven't found a similar announcement for other parts of the world so I guess it has mainly to do with the dollar - euro rate.

Security Bulletin: GNU C library (glibc) vulnerability affects DS8000 and XIV

IBM issued some security bulletins referring to all models of the DS8000 and the Gen2 and Gen3 of the XIV.

In general, here's what it's about :

"Summary

GNU C library (glibc) vulnerability that has been referred to as GHOST affects DS8000

Description: 

The gethostbyname functions of the GNU C Library (glibc) are vulnerable to a buffer overflow. By sending a specially crafted, but valid hostname argument, a remote attacker could overflow a buffer and execute arbitrary code on the system with the privileges of the targeted process or cause the process to crash. The impact of an attack depends on the implementation details of the targeted application or operating system. This issue is being referred to as the "Ghost" vulnerability."

For more information and fixes, please refer to the appropriate flashes.

Redbook : IBM z13 Configuration Setup

When introducing the new IBM z13 I also listed out some documentation including some redbooks. At that time one of them, the Configuration Setup redbook, wasn't available yet. You can now download a first draft from the 'deploy' section of the page specifically dedicated to IBM z13 I also mentioned previously.

The abstract of the Redbook :
"This IBM® Redbooks® publication helps you install, configure, and maintain the IBM z13. The z13 offers new functions that require a comprehensive understanding of the available configuration options. This book presents configuration setup scenarios, and describes implementation examples in detail.

This publication is intended for systems engineers, hardware planners, and anyone who needs to understand IBM z Systems configuration and implementation".
The table of contents :
Chapter 1. Introducing the IBM z13
Chapter 2. Channel subsystem
Chapter 3. Configuration planning
Chapter 4. Upgrading from an IBM zEC12 to IBM z13
Chapter 5. Replacing an IBM zEC12 with IBM z13
Chapter 6. Installing a new IBM z13
Chapter 7. Installing an extra IBM z13
Chapter 8. Server Time Protocol (STP)
Chapter 9. Crypto Express5S and Crypto Express4S configuration
Chapter 10. Logical partitions
Chapter 11. Preparing IBM z13 for zBX Model 004
Chapter 12. Flash Express
Chapter 13. Configure Open System Adaptor (OSA) and RoCE Express
Appendix A. Additional features and functions
I don't think it needs any more recommendations. If you're going to install a new IBM z13, this is a good place to start.
